Retrieving all values in a column

I am new to google apps script and I was trying to get all the values in a particular column inside a sheet named "Items". I was able to create a loop to get to the last row that contains value but when I try to use the function, no data is retrieved. I tried console.log(values[lr][0]); inside the if clause and it outputs just fine.
Here's my code
function getAllItems()
{
var ss= SpreadsheetApp.getActiveSpreadsheet();
var locationSheet = ss.getSheetByName("Items");
var values = locationSheet.getRange("Items!B2:B").getValues();
for(var i = values.length - 1 ; i >= 0 ; i--){
if (values[i][0] != null && values[i][0] != ""){
lr = i + 1;
values.sort();
return values[lr][0];
}
}
}

There are several ways to retrieve values from a column in Google Sheets.
The basics, getting the sheet
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = spreadsheet.getSheetByName('Items');
SpreadsheetApp.getActiveSpreadsheet() works in bounded projects and add-ons. Spreadsheet.getSheetByName(name) works when the sheet name is known.
Getting the column values by using Sheet.getRange and an open reference using A1 notation
var values = sheet.getRange('B:B').getValues();
If your spreadsheet has blank rows at the bottom, in this case Range.getValues besides the column values, it will return an empty string for each blank rows.
Besides using Sheet.getRange with an open reference, it might be used with other reference types and using start row, start column, number of rows and number of columns.
Getting the column values by using Sheet.getRange and an open reference using A1 notation excluding empty strings
var values = sheet.getRange('B:B').getValues().filter(String);
Getting the column values by using Sheet.getDataRange and Array.prototype.map
var values = sheet.getDataRange().getValues().map(row => row[1]);
Only will return the values from the first row to the last row of the data range. The data range is determined from A1 to the last row and last column having values, i.e., if one column B have values from row 1 to row 10 and column C have values from row 4 to row 20, the data range reference is A1:C20, so values will contain the values from row 1 to row 20, showing empty strings for the blank cells.
Getting the column values by using Sheet.getDataRange, Array.prototype.splice and Array.prototype.getLastIndex
var values = sheet.getDataRange().getValues();
values.splice(values.findLastIndex(String) + 1);
Only will return the values from the first row to the last row of the column containing non empty strings. This might be helpful when having columns "of different sizes", as explained in the previous case. Please note that if there blank cells in between, an empty string will be included as value of these cells.
Notes:
Instead of Range.getValues you might use Range.getDisplayValues to get the strings with the values formatted as strings as they are displayed on Google Sheets cells. Both methods return the values structured as an Array of Arrays, this might be handy if you will be adding the values to another range, but if you want to add them to the execution logs you might want to format them in another way.
Please bear in mind that if the column content is very large, nowadays a Google Sheets spreadsheet could have up to 10 million cells and each cell could have upto 50k characters, the column content will be truncated when printed to the execution logs.

Get column from a two dimensional array

Array

You don't need a loop for that (explanation in comments):
function getAllItems()
{
var ss= SpreadsheetApp.getActiveSpreadsheet();
var locationSheet = ss.getSheetByName("Items");
var values = locationSheet.getRange("Items!B2:B").getValues().flat(); // 2D -> 1D array
var filter_values = values.filter(r=>r!=''); // remove empty rows
Logger.log(filter_values); // get the full list
Logger.log(filter_values[filter_values.length-1]); // get the last value;
return filter_values[filter_values.length-1];
}

Try this:
function getAllItems(){
var ss= SpreadsheetApp.getActive();
var sh = ss.getSheetByName("Items");
var vs = sh.getRange("B2:B"+sh.getLastRow()).getValues();//all the values in column B
return sh.getLastRow();//the last row with data
}
Or you can use:
function getColumnHeight(col, sh, ss) {
var ss = ss || SpreadsheetApp.getActive();
var sh = sh || ss.getActiveSheet();
var col = col || sh.getActiveCell().getColumn();
var rcA = [];
if (sh.getLastRow()){ rcA = sh.getRange(1, col, sh.getLastRow(), 1).getValues().flat().reverse(); }
let s = 0;
for (let i = 0; i < rcA.length; i++) {
if (rcA[i].toString().length == 0) {
s++;
} else {
break;
}
}
return rcA.length - s;
//const h = Utilities.formatString('col: %s len: %s', col, rcA.length - s);
//Logger.log(h);
//SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(h).setWidth(150).setHeight(100), 'Col Length')
}
function getAllItems(){
var ss= SpreadsheetApp.getActive();
var sh = ss.getSheetByName("Items");
var vs = sh.getRange("B2:B"+getColumnHeight(2,sh,ss).getValues();//all the values in column B
return sh.getLastRow();//the last row with data
}
If you use filter() to filter out all of the nulls you may not get the desired result if one of the data elements is null.

Google Script return value from one sheet to another sheet

This is my first Google Script and I'm struggling a little bit while trying to bring back the values from a specific cell & sheet to another sheet.
I have a total of 18 columns, being the first one the ID which is going to be the input that the user would need to add in order to retrieve the data from one sheet to another. As the first one is the ID, and will be already be inputted by the user, I would need to retrieve the data from columns 2 to 18
Here is my code:
function SearchID() {
var columnIndex = 0;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var formS = ss.getSheetByName("Manual Costs App"); // App sheet
var str = formS.getRange("D6").getValue(); // The ID to search will be inputted here
var dataS = ss.getSheetByName("Inputs").getDataRange().getValues(); // Retrieving the data based on the user input
for (var i = 0; i<=dataS.length; i++) {
var row = dataS[i];
if (row[columnIndex] == str) {
formS.getRange("D9").setValue(row[1]);
formS.getRange("D13").setValue(row[2]);
formS.getRange("D14").setValue(row[3]);
formS.getRange("D15").setValue(row[4]);
formS.getRange("D16").setValue(row[5]);
formS.getRange("D18").setValue(row[6]);
formS.getRange("D19").setValue(row[7]);
formS.getRange("D20").setValue(row[8]);
formS.getRange("D21").setValue(row[9]);
formS.getRange("D22").setValue(row[10]);
formS.getRange("D23").setValue(row[11]);
formS.getRange("D25").setValue(row[12]);
formS.getRange("D26").setValue(row[13]);
formS.getRange("D27").setValue(row[14]);
formS.getRange("D28").setValue(row[15]);
formS.getRange("D29").setValue(row[16]);
formS.getRange("D30").setValue(row[17]);
break;
}
}
}
The link to a sample spreadsheet of what I'm building is here
Update: Everything is fixed now! What I did was removing the space in the for loop. After that, it retrieved the data but a TypeError: Cannot read property '0'. Also solved it adding a break after the loop to avoid it.

It's a type in your for loop, notice how spelled length:
for (var i = 1; i <= values.lenght; i++)
You also don't want to set values line by line like you do, get a longer range and set the values with setValues() rather than setValue(). There's quite a bit of refactoring to do there actually.

The user did found the answer and updated it on the question.

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.

Copy cell values from one google sheet to another based on condition

I'm having an issue with a script for Google sheets
I work in education, and basically we have some teachers who would like to have a form to use when they need to refer a student to an administrator.
So, we have a Google form set up and it's answers populate our "Master" tab within the sheet. Then we have a tab set up for each administrator, the idea being that we can write a function that moves data over based on the contents of the "administrator assigned" box (ColumnT in the code below)
The first bit I need to get functional is the code that handles that part, here's what I've been able to come up with (Heavily commented so that you can hopefully see my thought process):
//Get the active spreadsheet and store in a variable
function importStudName() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
//Get"Master" spreadsheet and store in a variable
var master_sheet = ss.getSheetByName("Master");
//Get "Miranda" spreadhseet and store in a variable
var miranda_sheet = ss.getSheetByName("Miranda");
//Column T
var columnT = master_sheet.getSheetValues(0, 20, 0, -1);
//Column D
var columnD = master_sheet.getSheetValues(0, 4, 0, -1);
//Column E
var columnE = master_sheet.getSheetValues(0, 4, 0, -1);
//Loop through Column T and find every value that = "Miranda"
for(var i = 0; i <= columnT; i++) {
if (columnT[i] === "Miranda") {
//Set a variable to hold the last row in the "Miranda" sheet
var miranda_row = (miranda_sheet.getLastRow() + 1);
//Make the row with the "Miranda" string active
//Set a variable that concatenates the Column D and Column E variables (from "master" sheet) into a string
//Copy the new variable to the "Miranda" sheet
.copyValuesToRange(miranda_sheet, 1, 1, miranda_row, miranda_row);
}
}
}
Mostly, I can't seem to figure out the bit that would make select the row that has the "Miranda" keyword in it. Once I had that down, I think it's just a matter of using the .getRange() function to pull the values from columnD and columnE.
I'm a bit rusty on my JavaScript, and this is the first time I've written something for apps script. So it's possilble I'm going about this all wrong :)
Any suggestions would be welcome

The method getSheetValues returns "Object[][] — a two dimension array of values". So, its entries should be accessed as values[i][j] where i is row offset from the upper left corner of the range, and j is the column offset. In particular, your Miranda comparison should be
if (columnT[i][0] === "Miranda")
Another remark: the row and column numbers in Sheets begin with 1, unlike JavaScript array indices. Passing (0, 20, 0, -1); in getSheetValues indicates you may be miscounting things.
Finally, I'd recommend using .getRange(...).getValues() instead of getSheetValues(). For one thing, you can pass A1 notation to getRange, like
var valuesT = sheet.getRange("T1:T").getValues();
to get all values in column T. If it's preferable to not fetch a bunch of empty cells at the bottom, one can use
var lastRow = sheet.getLastRow();
var valuesT = sheet.getRange("T1:T" + lastRow).getValues();

Delete Row Based on Active Cell

I am trying to delete a row's data based on the active cell. I have looked through Google's documentation and I cannot figure out how to do this. I have also searched the forums and found a couple of similar scenarios, but I cannot get it to work. I tried to do this by lopping through an array of data and deleting the row based on the value in the array, but this does not work either. I am sure that I am overcomplicating things here. Here is the code that I have so far...
function clearProject() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var source = ss.getSheetByName('Projects');
var sourceArray = source.getRange(1,1,10).getValues();
var sourceCell = source.getActiveCell();
var sourceData = sourceCell.getValues();
//var sourceRow = sourceCell.getRange(sourceCell, );
var target = ss.getSheetByName('Timeline').getRange(1, 1, 10).getValues();
for (var i = 0; i < sourceArray.length; i++){
if(i == sourceData){
sourceCell.clearContent();
}
}
Thank you for any help that you can afford!

First of all you cannot compare like this if(i == sourceData) due to getValues returns
...the rectangular grid of values for this range. Returns a
two-dimensional array of values, indexed by row, then by column. The
values may be of type Number, Boolean, Date, or String, depending on
the value of the cell. Empty cells will be represented by an empty
string in the array. Remember that while a range index starts at 1, 1,
the JavaScript array will be indexed from [0][0].
And I didn't catch your goal, could you plesae add some more explanation?

It could be as simple as that :
function delRowsInActiveRange() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var source = ss.getActiveRange();
var height = source.getValues().length;
var rowPosition = source.getRowIndex();
ss.getActiveSheet().deleteRows(rowPosition, height);
}
This function deletes all the rows that include selected cells.
