Google Sheets Custom Script iterate through a range and print values in a determined order

UPDATE WITH a-change 's response and code
I am working on a function that will let me select a range in a sheet in Google Sheets and then paste the values that I am interested in into a specific order on another sheet.
Suppose RawData (Sheet1) looks like this:
I want to grab the range RawData!A1:L15, so basically everything that is that picture.
Afterwards I want to print it in another sheet (Sheet2 called Analysis) like so:
So far this is the code:
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("RawData");
var targetSheet = ss.getSheetByName("Analysis");
var range = sheet.getDataRange();
var values = range.getValues();
for (var i in values) {
var row = values[i];
var column = 1;
for (var j in row) {
var value = row[j];
if (value !== "X") {
targetSheet.getRange(parseInt(i) + 1, column).setValue(value);
column++;
}
}
}
}
This code results in values being pasted in the 'Analysis' with the same order as in the 'RawData' sheet. The idea is for the data to be able to be pasted in a trio format, with no spaces between values. So the first trio would be: A1 = 1, B1 = 2, C1 = 3, A2 = 4, B2 = 5, C2 = 6, and so on.

A couple of things:
for (var row in values) { — here row is an index of an element, not the element itself. So it'll always be not equal to "X". Better to put it this way:
for (var i in values) {
var row = values[i];
}
Then you need to iterate over row to get to a single element and compare it with "X":
for (var i in values) {
var row = values[i];
for (var j in row) {
var value = row[j];
if (value !== "X") {
}
}
}
Next thing is pasting the value to your target sheet. The reason you are getting the same number in all the cells is that you're calling setValue on the whole A1:C8 cells range instead of one particular cell.
for (var i in values) {
var row = values[i];
var column = 1;
for (var j in row) {
var value = row[j];
if (value !== "X") {
targetSheet.getRange(parseInt(i + 1), column).setValue(value);
column++;
}
}
}
targetSheet.getRange(i, j) here gives you a single-cell precision.
So alltogether your code would look something like:
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("RawData");
var targetSheet = ss.getSheetByName("Analysis");
var range = sheet.getDataRange();
var values = range.getValues();
for (var i in values) {
var row = values[i];
var column = 1;
for (var j in row) {
var value = row[j];
if (value !== "X") {
targetSheet.getRange(parseInt(i) + 1, column).setValue(value);
column++;
}
}
}
}
See how the target sheet is set as a variable instead of using a range on the source sheet — it gives you more readability and freedom
It seems that when iterating like for (var i in row) i is considered to be a string so the parseInt call
column variable is needed to make sure there are no empty cells in the target sheet
I've also changed sheet.getRange(1,1,15) to sheet.getDataRange() to make sure your code gets all the data in the sheet
The approach of setting values into single cells separately is not optimal. It should work for you in your case as the data range seems pretty small but as soon as you get to hundreds and thousand of rows, you'll need to switch to setValues, so you'll need to build a 2D-array before pasting the values. The tricky thing is that your resulting rows may have a variable number of items (depending on how many Xs are in a row) while setValues expects all the rows to be of the same length — it's possible to get round it of course.

Remove duplicates across multiple sheets

I want to remove duplicates across 2 different sheets.
I have my active sheet, and I want to remove duplicates that already exist in my sheet "Blacklist". I want to run this process for both Column A and Column B (or simply for any values across the entire sheets). When a duplicate is found, I want to leave the row in tact but replace the value with '' (e.g. an empty cell).
I have a working version I mangled together, but only for the active sheet.
N.B. it's the findDuplicate function that I use, the removeDuplicate function I left there not to mess anything up :)
// this is a Google Apps Script project
function onOpen() {
var spreadsheet = SpreadsheetApp.getActive();
var menuItems = [
{ name: 'Find duplicates...', functionName: 'findDuplicate' },
{ name: 'Remove duplicates...', functionName: 'removeDuplicate' }
];
spreadsheet.addMenu('Duplicates', menuItems);
}
function removeDuplicate() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getActiveRange();
var data = range.getValues();
var rowNum = range.getRow();
var columnNum = range.getColumn();
var columnLength = data[0].length;
var uniqueData = [];
var duplicateData = [];
// iterate through each 'row' of the selected range
// x is
// y is
var x = 0;
var y = data.length;
// when row is
while (x < y) {
var row = data[x];
var duplicate = false;
// iterate through the uniqueData array to see if 'row' already exists
for (var j = 0; j < uniqueData.length; j++) {
if (row.join() == uniqueData[j].join()) {
// if there is a duplicate, delete the 'row' from the sheet and add it to the duplicateData array
duplicate = true;
var duplicateRange = sheet.getRange(
rowNum + x,
columnNum,
1,
columnLength
);
duplicateRange.deleteCells(SpreadsheetApp.Dimension.ROWS);
duplicateData.push(row);
// rows shift up by one when duplicate is deleted
// in effect, it skips a line
// so we need to decrement x to stay in the same line
x--;
y--;
range = sheet.getActiveRange();
data = range.getValues();
// return;
}
}
// if there are no duplicates, add 'row' to the uniqueData array
if (!duplicate) {
uniqueData.push(row);
}
x++;
}
}
function findDuplicate() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getActiveRange();
var data = range.getValues();
var rowNum = range.getRow();
var columnNum = range.getColumn();
var columnLength = data[0].length;
var uniqueData = [];
// iterate through each 'row' of the selected range
for (var i = 0; i < data.length; i++) {
var row = data[i];
var duplicate = false;
// iterate through the uniqueData array to see if 'row' already exists
for (var j = 0; j < uniqueData.length; j++) {
if (row.join() == uniqueData[j].join()) {
// if there is a duplicate, highlight the 'row' from the sheet
duplicate = true;
var duplicateRange = sheet.getRange(
rowNum + i,
columnNum,
1,
columnLength
);
duplicateRange.setValue('');
}
}
// if there are no duplicates, add 'row' to the uniqueData array
if (!duplicate) {
uniqueData.push(row);
}
}
}
Thanks so much for your help! I've been at this for a few hours and figured I should just ask the experts for advice :)

The first lines of both your removeDuplicate and findDuplicate function seems indeed to indicate that you refer to the active spreadsheet / sheet / range
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getActiveRange();
var data = range.getValues();
If you want to be able to use the same function for a given spreadsheet / sheet / range which is not the active one, you will need to use other functions than the getActiveXXX().
For example, to get the sheet named "Blacklist", you should use
sheet = spreadsheet.getSheetByName("Blacklist")
(see also https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#getsheetbynamename)
If you want to access a specific range which differs from the active range, you should use the getRange method (see also https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#getrangea1notation)
Note that getRange method can be used in different ways, e.g.
getRange("A1:D4"), getRange(1, 1, 3, 3) (the parameters being respectively startRow, startColumn, numRows,numColumns)
Additionally, if you don't want to hardcode the last line of your 2 columns, you will most probably need this function to find the last line in the code :
https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#getlastrow
(there is also an example there showing how to use getRange() in combination with getLastRow()).
I hope this will help you going further.
Please note that I didn't check the rest of your code and just assumed that your deduplication logic works fine as you mentioned it in your commment.
Good luck !

Pop up dialog box is value is duplicate

I am trying to create a google script that will scan through a specific column of one google sheet and check if any new additions are a duplicate. I have come up with the following, but it isn't working.
function hasDuplicates() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Customer and form Details");
var array = sheet.getRange('B2:B' + lastRow).getValues();
var valuesSoFar = [];
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (value in valuesSoFar) {
SpreadsheetApp.getUi().alert('Hello, world!');
}
else{
valuesSoFar.push(value);
}
}
}
As far as Im aware the above code creates an array called array and populates it with the specific range I am interested in. I then create a new, empty, array called valuesSoFar. The code then loops through the column and sequentially checks if that item has already been seen before, if so it gives you an alert. If not it adds it to the list of new items and keeps going.

It looks a bit like you are using the online documentation code.
But the following assignment is missing:
var lastRow = sheet.getLastRow();
or just replace lastRow with sheet.getLastRow()
Update:
I assume that the following solution should work if you actually have any duplicates in your column B:
function hasDuplicates() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Customer and form Details");
var array = sheet.getRange('B2:B' + sheet.getLastRow()).getValues();
var valuesSoFar = [];
for (var i = 0; i < array.length; ++i) {
var value = array[i][0];
if (value in valuesSoFar) {
SpreadsheetApp.getUi().alert('Hello, world!');
} else {
valuesSoFar.push(value);
}
}
}
If it isn't working yet, I am sorry.
As long as you can not provide any information on what kind of error you are running into, I will not look into this anymore.

Ignore empty rows from a loop in Google Apps Script

I'm new to Google Apps Script and I'm trying to ignore the empty rows from a for loop, but I'm still getting the empty rows in my log. Here are my codes,
function getNonEmptyRows() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet1 = ss.getSheetByName("Bldng4");
var lr = sheet1.getLastRow() - 17;
for (var i = 1; i < lr; i++) {
var singleRow = sheet1.getRange(i, 1, 1, sheet1.getLastColumn()).getValues();
if (singleRow.length > 0) {
Logger.log(singleRow);
}
}
}
How can I get the only non empty rows from the loop? Need this help badly. Thanks.

var range_data =
sheet1.getRange("A2:A") //Column Range
.getValues() //Get array from range values
.filter(array=>array != '') //Filter non-empty values

I was looking for a solution to a similar problem and here is what I did:
first, I found this tutorial on how to create google apps script to eliminate duplicate rows.
next, i modified it like this to eliminate empty rows:
function removeEmptyRows() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("settings");
var data = sheet.getRange("A2:D").getValues();
var newData = new Array();
for(i in data){
var row = data[i];
var empty = false;
for(i in data){
if(row.toString() == ",,,"){
empty = true;
}
}
if(!empty){
newData.push(row);
}
sheet.getRange(2, 6, newData.length, newData[0].length).setValues(newData);
};
As you can see, it takes A2:D range, removes empty rows and then pastes filtered data without empty rows into range F2:I.
You can try to use this script, but you may need to adjust it to "width" of your array. To do so change the number of commas in the following string:
if(row.toString() == ",,,"){
edit:
I modified script a bit to automatically adjust to width of your array:
function removeEmptyRows() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("settings");
var range = sheet.getRange("A2:C");
var data = range.getValues();
var dataWidth = range.getWidth();
var newData = new Array();
if (dataWidth<=1) {
var stringToCompare = '';
}else{
var stringToCompare = ',';
for (var i=0;i<dataWidth-2;i++) stringToCompare+=","
};
for(i in data){
var row = data[i];
var empty = false;
for(i in data){
if(row.toString() == stringToCompare){
empty = true;
}
}
if(!empty){
newData.push(row);
}
}
sheet.getRange(2, 6, newData.length, newData[0].length).setValues(newData);
};

The getValues() method you are using always return a 2 dimensions array, whatever the contents of the cells might be. There are several ways to get the cells content, one of them is to stringify the range content (convert matrix to single string) , remove the commas (and eventually "invisible" spaces) and check the length of the resulting string.
replacement code could go like this :
var singleRow = sheet1.getRange(i, 1, 1, sheet1.getLastColumn()).getValues().toString().replace(',','').replace(' ','');
That said, this code is very inefficient because it uses SpreadSheetApp service in each loop iteration which is particularly slow.
You'll find better approches in the documentation about best practices.

Google Apps Script: how to get the number of columns in a sheet? (alternative way)

I want to use the number of columns in a sheet in a for loop. I could use a function like this, to stop when the loop finds the first empty column:
function getRowAsArray(sheet, row) {
var dataRange = sheet.getRange(row, 1, 1, 99);
var data = dataRange.getValues();
var columns = [];
for (i in data) {
var row = data[i];
Logger.log("Got row", row);
for(var l=0; l<99; l++) {
var col = row[l];
// First empty column interrupts
if(!col) {
break;
}
columns.push(col);
}
}
return columns;
}
But I'd like an alternative function which use the number of columns in the sheet. How can I do that?

Please have a look at the documentation:
getLastColumn() and to get the maximum count including empty ones, getMaxColumns().
