How to retrieve a particular row from an array in google apps script?

I am using google sheets quite a lot, but now I am trying to use google apps script to get and update dynamic data retrieved from formulas into a static table.
So, I have a sheet called 'dynamique', with formulas retrieving, filtering and sorting data from other spreadsheets.
I want to be able to work on this data, so I am trying to create a button which would copy all the values from the 'dynamique' sheet into another sheet called 'statique'. That is, I want a formula which would check if the values from the column C of the 'dynamique' sheet are in the column C of the 'statique' sheet. And if the values aren't there, I want the script to copy them. (columns A and B are empty)
I've managed to get my script to work for one column, but now, I want to copy the whole line.
For example, if the value in dynamique!C10 can't be found in statique!C:C, my script writes the value of dynamique!C10 in the first empty cell of the column statique!C:C. But I want it to write dynamique!C10:J10 into my destination sheet (say it's going to be maybe statique!C8:J8).
Here is my code, working for only one cell.
function dynamicToStatic() {
var dynSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("dynamique");
var staSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("statique");
var dynLength = dynSheet.getRange("C1:C").getValues().filter(String).length;//.getLastRow();
var staLength = staSheet.getRange("C1:C").getValues().filter(String).length;
var staRange = staSheet.getRange(6,3,staLength-1);
var staValues = staRange.getValues();
var rangeToCheck = dynSheet.getRange(6,3,dynLength-1,8);
var valuesToCheck = rangeToCheck.getValues();
var numRows = rangeToCheck.getNumRows();
var staNumRows = staRange.getNumRows();
for (i = 0; i<= numRows; i++) {
var row = valuesToCheck[i];
var index = ArrayLib.indexOf(staValues , -1 , row);
if (index == -1) {
//if (staValues.indexOf(row) != -1) {
staSheet.getRange(i+6,3,1,8).setValues(row);
}
}
var timestamp = new Date();
staSheet.getRange(4,3).setValue('List updated on the: '+timestamp);
}
Now I can't manage to retrieve the whole line of the array, so as to be able to copy it using range.setValues(). I always get error messages.
Any help would be more than appreciated...

function gettingFullRows() {
const ss=SpreadsheetApp.getActive();
const sh=ss.getSheetByName('Sheet1');
const shsr=2;//data startrow
const vA=sh.getRange(shsr,1,sh.getLastRow()-shsr+1,sh.getLastColumn()).getValues();
let html='';
vA.forEach((r,i)=>{
html+=Utilities.formatString('<br />Row:%s is %s',i+shsr,r.join(','));
});
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html), "Row");
}

So i did some re-writing to your code and made some comments in there. I hope this will make some things clear.
Array's are 0 indexed. So if the value is NOT found in the .indexOf then it would return -1. Also (for speed) i first push all the result to a array and then set the array in one "action" this saves a lot of time. The calls to and from a sheet takes the most time.
For the conversion to a 1d array i used spread operator
See this link for difference in const / var / let
The timestamp string i updated with the use of Template literals
If you have some questions, shoot! (also i did not test this ofcourse)
function dynamicToStatic() {
const dynSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("dynamique");
const staSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("statique");
const dynValues = dynSheet.getRange(1,3,dynSheet.getLastRow(),8).getValues();
//This is a 2d array
const staRaw = staSheet.getRange(6, 3, staSheet.getLastRow()).getValues();
//Convert to 1d array, for the indexoff later on, this way it is easier.
const staValues = [].concat(...staRaw);
//to store the output, as a 2d array, inside the if you see i push it in as array so you have the 2d array for the setValues.
const output = [];
for (let i = 0; i < dynValues.length; i++){
//i = the index of the array (row) inside the array of rows, the 0 would be the values of column C.
if (staValues.indexOf(dynValues[i][0]) >= 0){
output.push([dynValues[i]]);
}
}
//Start by the lastrow + 1, column C(3), ouput is a array of arrays(rows), then get the [0].lengt for the columns inside the row array.
staSheet.getRange(staSheet.getLastRow()+1, 3, output.length, output[0].lenght).setValues(output);
const timestamp = new Date();
staSheet.getRange(4,3).setValue(`List updated on the: ${timestamp}`);
}

How to combine the getRange() function with a forLoop when trying to piece together your data in Google Apps Script?

EDIT:
Since my problem is rather difficult to describe I added an example of my data which hopefully shows what I'd like to achieve:
https://docs.google.com/spreadsheets/d/1Wa_z2e2br53usul3uMy8nczXushvhPFRiIlZ5M2ueYU/edit?usp=sharing
I hope it's okay to do so.
I could need some help with the following problem: I'm trying to create a summary sheet for a variety of data sheets. Each data sheet, i.e., "Sheet1", "Sheet2", "Sheet3", e.g., has an ID variable that I use for splitting my data within each data sheet.
What I'm trying to do is to loop through all my data sheets, grab the data in each sheet, split the data for each sheet by ID, so that I have all rows with As, Bs and Cs for each sheet, and then put all these pieces together BUT SEPARATED BY A COUPLE OF EMPTY ROWS in my summary sheet.
What I have done thus far is this:
function main() {
// SETUP.
var app = SpreadsheetApp;
var workbook = app.getActiveSpreadsheet();
var activeSheet = workbook.getActiveSheet();
// CREATE NEW SUMMARY SHEET.
var targetSheet = workbook.getSheetByName("Summary");
if (!targetSheet) {
workbook.insertSheet("Summary",1);
}
// ARRAY OF SHEETS USED IN MY LOOP.
var tabs = ["Sheet 1",
"Sheet 2",
"Sheet 3"];
// LOOP FOR ALL SHEETS.
for (var i = 0; i < tabs.length; i++) {
var sheet = workbook.getSheetByName(tabs[i]);
// GRAB THE ORIGINAL DATA.
var originalData = sheet.getRange(5, 1, sheet.getLastRow()-5, sheet.getLastColumn()).getValues();
// SELECT ID AND SORT BY UNIQUE IDs.
var range = sheet.getRange(5,2,sheet.getLastRow()-5,1).getValues();
var range = [].concat.apply([], range);
let uniqueValues = range.filter((v, i, a) => a.indexOf(v) === i);
// GRAB THE UNIQUE DATA PIECES IN EACH SHEET.
for (var t = 0; t < uniqueValues.length; t++) {
var filterText = uniqueValues[t];
var newData = originalData.filter(function(item) {
return item[1] === filterText;
});
// DO SOMETHING I HAVE YET TO DEFINE
// e.g., exclude rows that fall beneath a certain threshold.
// WRITE DATA PIECES BACK TO SUMMARY SHEET.
workbook.getSheetByName("Summary").getRange(???).setValues(newData);
}
}
}
The code above works fine and does slice my data on different data sheets correctly. However, setting the pieces back together is an issue. Right now the data pieces of each iteration is overwritten by the next one.
What I need to do is to figure out a way how to grab these different slices of data based on my ID and then put them together in a way shown in my example data (linke above).
I think I'm lost somewhere between different loops and the data stored temporarily within the loops.

Answer:
After gathering the data you need to:
Run through the rows
Check the product name
Push rows with the same product name to separate arrays
Use setValues() to set the data of each product
Add 4 blank rows
Code Modifications:
Before your LOOP THROUGH ALL SHEETS for loop, add an array declaration:
var dataSets = [];
Then, replace the following line:
workbook.getSheetByName("Summary").getRange(???).setValues(newData);
With:
dataSets.push(newData);
And after the for loop, do the data processing set out in the first section of this answer:
// Create a 2D array to push the data to:
var allData = [[],[],[]];
// loop through the Data sets and push them to the correct element of allData:
dataSets.forEach(function(dataSet) {
dataSet.forEach(function(row) {
if (row[1] == "Product A") {
allData[0].push(row)
}
else if (row[1] == "Product B") {
allData[1].push(row)
}
else if (row[1] == "Product C") {
allData[2].push(row)
}
})
})
// Define the next row to add data to in the Summary sheet:
var nextRow = 1;
// Set the data to the Summary sheet:
allData.forEach(function(product) {
var noOfColumns = product[0].length;
var noOfRows = product.length;
workbook.getSheetByName("Summary").getRange(nextRow, 1, noOfRows, noOfColumns).setValues(product)
nextRow += noOfRows + 4;
});

How to document merge a parent record and all of its child records

I'm creating a document merge (mail merge) from Google App Maker to a Google Document template. I can do so successfully when merging one single record, but how do you merge several records into the one document?
I have an purchase_orders parent record which has several purchase_order_line_items child records but I can't seem to get all of these records into a single document merge.
A similar question (Document Merge with Google App Maker) was asked by by Johan W with a comprehensive answer by Markus Malessa and Pavel Shkleinik (thank you!). However, it only caters for cases when you are merging one single record.
I have tried to build on their answer by using a second for loop to get the data of all associated child records. The script runs but only seems to merge the first child record; not all of them.
Here is an example of the server-side code I've tried to use:
function Export(key, key2) {
// Get the parent record by its key, which was passed by the first parameter above
var record = app.models.Purchase_Orders.getRecord(key);
// Get the first child record by its key, which was passed by the second parameter above
var childRecord = app.models.Purchase_Order_Line_Items.getRecord(key2);
// Get the Google Document which will be used as a template for this merge
var templateId = '1Xbt8camqHJYrhBnx0a6G2-RvTvybqU0PclHifcdiLLA';
//Set the filename of the new merge document to be created
var filename = 'Document for Customer ' + new Date();
//Make a copy of the template to use as the merge document
var copyFile = DriveApp.getFileById(templateId).makeCopy(filename);
//Get the Google Docs ID of the newly created merge document
var copyDoc = DocumentApp.openById(copyFile.getId());
var copyBody = copyDoc.getBody();
// Replace the field names in the template with the field data from the parent record
var fields = app.metadata.models.Purchase_Orders.fields;
for (var i in fields) {
console.log(i);
var text = '<<' + fields[i].name + '>>';
var data = record[fields[i].name];
if (data !== null) {
copyBody.replaceText(text, data);
} else {
// do nothing
}
}
// Replace the field names in the template with the field data from the child records
childFields = app.metadata.models.Purchase_Order_Line_Items.fields;
for (i in childFields) {
console.log(i);
var childtext = '<<' + childFields[i].name + '>>';
var childdata = childRecord[childFields[i].name];
if (childdata !== null) {
copyBody.replaceText(childtext, childdata);
} else {
// do nothing
}
}
}
How can I improve my code so that all associated child records are merged into a single document?
How can I set up my Google Document template to cater for any number of child records?

Rather than passing in the child record key via a second parameter, I would suggest just passing in the parent key and then changing your function as follows:
function Export(key) {
// Get the parent record by its key, which was passed by the first parameter above
var record = app.models.Purchase_Orders.getRecord(key);
// Get the first child record by its key, which was passed by the second parameter above
var childRecords = record.Purchase_Order_Line_Items;
// Get the Google Document which will be used as a template for this merge
var templateId = '1Xbt8camqHJYrhBnx0a6G2-RvTvybqU0PclHifcdiLLA';
//Set the filename of the new merge document to be created
var filename = 'Document for Customer ' + new Date();
//Make a copy of the template to use as the merge document
var copyFile = DriveApp.getFileById(templateId).makeCopy(filename);
//Get the Google Docs ID of the newly created merge document
var copyDoc = DocumentApp.openById(copyFile.getId());
var copyBody = copyDoc.getBody();
// Replace the field names in the template with the field data from the parent record
var fields = app.metadata.models.Purchase_Orders.fields;
for (var i in fields) {
console.log(i);
var text = '<<' + fields[i].name + '>>';
var data = record[fields[i].name];
if (data !== null) {
copyBody.replaceText(text, data);
} else {
// do nothing
}
}
// Replace the field names in the template with the field data from the child records
var childFields = app.metadata.models.Purchase_Order_Line_Items.fields;
var table = [];
var tableheader = [];
for (i in childFields) {
console.log(i);
tableheader.push(childFields[i].displayName);
}
table.push(tableheader);
for (i in childRecords) {
var data = [];
for (var j in childFields) {
data.push(childRecords[i][childFields[j].name]);
}
table.push(data);
}
copyBody.appendTable(table);
The table building is based on a 2D array and the documentation is here https://developers.google.com/apps-script/reference/document/table. But you will also need to remove your prebuilt table in favor of just appending a table instead. This way you are not dependent on the quantity of child records being fixed like they currently are in your document template. Also, the variable for childRecords may or may not work, I have not tested this since I am unsure if prefetch works in conjunction with .getRecord(key). This may require some additional testing but hopefully this will provide enough guidance.
Thought I would add this as an alternative. Lets say you keep your table but remove all the rows with exception for the header row then you could still use DocumentApp service to add your rows to the table like so:
var tableheaderfieldnames = ['Quantity_for_PO', 'Inventory_Item.id', 'Unit_Price']; //set a fixed table header with the field names, uncertain if the table header for the related inventory item will work or not
var table = copyBody.getTables()[0];
for (i in childRecords) {
var row = table.appendRow();
for (var j in tableheaderfieldnames) {
row.appendTableCell(childRecords[i][tableheaderfieldnames[j]]);
}
}
Keep in mind that AM does not allow you to use FK references, so for your inventory item that appears to use a fk field you may need to tinker around with setting the proper name reference for when you are trying to fill in the item in your table.

Google apps script - using for loop to pull data from range based on condition

I'm having an issue pulling the correct values out of a for loop in Google Sheets.
Here's my code:
Note: this is a snippet from a larger function
function sendEmails() {
var trackOriginSheet = SpreadsheetApp.getActiveSpreadsheet().getName();
var getMirSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Miranda");
//Set a new object to hold conditional data
var holdingData = new Object();
//Create function to get values from origin sheet
var returnedValues = function (trackOriginSheet) {
//Load dynamic variables into an object via returnedValues()
if (trackOriginSheet === getMirSheet) {
var startMirRow = 2; // First row of data to process
var numRowsMir = 506; // Number of rows to process
// Fetch the range of cells A2:Z506
var dataRangeMir = getMirSheet.getRange(startMirRow, 1, numRowsMir, 26);
// Fetch values for each cell in the Range.
var dataMir = dataRangeMir.getValues();
for (var k in dataMir) {
var secondRowMir = dataMir[k];
var intRefDescMir = secondRowMir[3];
var intAdminActionsMir = secondRowMir[4];
//Push returned data to holdingData Object
holdingData.selectedData = secondRowMir;
holdingData.refDesc = intRefDescMir;
holdingData.adminActions = intAdminActionsMir;
}
}
}
Here's a copy of the sheet I'm working on
What I need to have happened here first, is track the origin sheet, then create an object to hold data returned from the returnedValues() function. Later, I'll call the properties of this object into a send email function.
The problem is that I need to be able to pull data from the selected sheet dynamically (the "Miranda" sheet in this case.) In other words, when a user selects the "Yes" option in column I of the Miranda sheet, the first thing this script needs to do is pull the values of the variables at the top of the for loop within the same row that the user selected "Yes." Then, I'm pushing that data to a custom object to be called later.
It's apparent to me, that I'm doing it wrong. There's, at least, something wrong with my loop. What have I done? :)
EDIT:
After reviewing the suggestion by VyTautas, here's my attempt at a working loop:
for (var k = 0; k < dataMir.length; k++) {
var mirColI = dataMir[k][8];
var mirRefDesc = dataMir[k][2];
var mirAdminActions = dataMir[k][3];
var mirDates = dataMir[k][4];
if (mirColI === "Yes") {
var activeRowMir = mirColI.getActiveSelection.getRowIndex();
//Pull selected values from the active row when Yes is selected
var mirRefDescRange = getMirSheet.getRange(activeRowMir, mirRefDesc);
var mirRefDescValues = mirRefDescRange.getValues();
var mirAdminActionsRange = getMirSheet.getRange(activeRowMir, mirAdminActions);
var mirAdminActionsValues = mirAdminActionsRange.getValues();
var mirDatesRange = getMirSheet.getRange(activeRowMir, mirDates);
var mirDatesValues = mirAdminActionsRange.getValues();
var mirHoldingArray = [mirRefDescValues, mirAdminActionsValues, mirDatesValues];
//Push mirHoldingArray values to holdingData
holdingData.refDesc = mirHoldingArray[0];
holdingData.adminActions = mirHoldingArray[1];
holdingData.dates = mirHoldingArray[2];
}
}

Where did all that whitespace go in the actual script editor? :D
You already correctly use .getValues() to pull the entire table into an array. What you need to do now is have a for loop go through dataMir[k][8] and simply fetch the data if dataMir[k][8] === 'Yes'. I also feel that it's not quite necessary to use for (var k in dataMir) as for (var k = 0; k < dataMir.length; k++) is a lot cleaner and you have a for loop that guarantees control (though that's probably more a preference thing).
You can also reduce the number of variables you use by having
holdingData.selectedData = mirData[k]
holdingData.refDesc = mirData[k][2] //I assume you want the 3rd column for this variable, not the 4th
holdingData.adminActions = mirData[k][3] //same as above
remember, that the array starts with 0, so if you mirData[k][0] is column A, mirData[k][1] is column B and so on.
EDIT: what you wrote in your edits seems like doubling down on the code. You already have the data, but you are trying to pull it again and some variables you use should give you an error. I will cut the code from the if, although I don't really see why you need to both get the active sheet and sheet by name. If you know the name will be constant, then just always get the correct sheet by name (or index) thus eliminating the possibility of working with the wrong sheet.
var titleMirRows = 1; // First row of data to process
var numRowsMir = getMirSheet.getLastRow(); // Number of rows to process
// Fetch the range of cells A2:Z506
var dataRangeMir = getMirSheet.getRange(titleMirRows + 1, 1, numRowsMir - titleMirRows, 26); // might need adjusting but now it will only get as many rows as there is data, you can do the same for columns too
// Fetch values for each cell in the Range.
var dataMir = dataRangeMir.getValues();
for (var k = 0; k < dataMir.length; k++) {
if (dataMir[k][7] === 'Yes') { //I assume you meant column i
holdingData.refDesc = dataMir[k] //this will store the entire row
holdingData.adminActions = dataMir[k][3] //this stores column D
holdingData.dates = dataMir[k][4] //stores column E
}
}
Double check if the columns I have added to those variables are what you want. As I understood the object stores the entire row array, the value in column called Administrative Actions and the value in column Dates/Periods if Applicable. If not please adjust accordingly, but as you can see, we minimize the work we do with the sheet itself by simply manipulating the entire data array. Always make as few calls to Google Services as possible.

Updating a sheet with a value if strings match on two sheets

Sheet 2 has all the items and their statuses, while Sheet 1 has only some of the items from Sheet 2. I want to be able to see every time an item mentioned on Sheet 1 is listed as having a status update, i.e. e date, on Sheet 2.
Here's what I have so far, but having trouble calling the right range to work with. Is there a simpler way to do what I want to do?
function statusupdate() {
var activesht = SpreadsheetApp.getActiveSpreadsheet();
var statussht = activesht.getSheetByName("Sheet 2"); //get sheet on which status update occurs
var statusrng1 = statussht.getRangeByName('B');
var statusrng2 = statussht.getRangeByName('C');
var mainsht = activesht.getSheetByName("Sheet 1"); //get sheet where you show a specific thing has been updated, if that thing mentioned here.
var mainrng = mainsht.getRangeByName('F');
if (statusrng1 == mainrng) {
var date = statusrng2.getValue();
var daterng = mainrng.getRangeByName('E');
daterng.setValues(date);
}
}

Spreadsheet formula
You can have the rows in one sheet follow those in another without using a script. For example, say we have a sheet named Items that contains one row for every item we carry, with the item number in the first column.
We can use VLOOKUP() to search for the row containing info about individual items, and select specific columns from it.
For example, this formula would be used in B2, and could be copied to other cells in our sheet:
=VLOOKUP($A2,Items!$A$2:$C$7,COLUMN(),false)
Script
There are a few issues with your script.
.getRangeByName('B') - This method gets a named range. Given the name, I suspect you mean to get column B, and NOT a named range. If that's the case, you could use this instead:
var statusrng1 = statussht.getRange('B:B');
In A1Notation, the range B:B is the entire column B.
You intend to copy values, so there is another step required beyond identifying ranges; you need to first read the values from a range, and then later write them to a different range. For that, you need to use methods like getValues() and setValues().
Here's an updated version of your script, adapted to the example spreadsheet described above.
function statusupdate() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
//get sheet on which status update occurs
var statusSheet = ss.getSheetByName("Items");
var statusRange = statusSheet.getDataRange();
var statusData = statusRange.getValues();
//get sheet where you show a specific thing has been updated, if that thing mentioned here.
var trackingSheet = ss.getSheetByName("Tracking");
var trackingRange = trackingSheet.getDataRange();
var trackingData = trackingRange.getValues();
// Loop over all rows in the Tracking sheet to update from the Items sheet
// Start with row=1, because row 0 contains headers
for (var row=1; row<trackingData.length; row++) {
var item = trackingData[row][0];
if (item == '') continue; // skip rows without item #
// Look for item in Items sheet
var statusRow = null;
for (var sRow=1; sRow<statusData.length; sRow++) {
if (statusData[sRow][0] == item) {
// Found our match, grab that row
statusRow = statusData[sRow];
break;
}
}
// If we found a matching row, copy the status
if (statusRow) {
// Customize this depending on how your sheets are organized
trackingData[row][1] = statusRow[1];
trackingData[row][2] = statusRow[2];
}
}
// All values have been copied to trackingData, now write to sheet
trackingRange.setValues(trackingData);
}
