How to Set Up a Google Sheets ForEach Loop (2024 Guide)

Can You Set Up a ForEach Loop in Google Sheets?

You can simulate the behavior of a ForEach loop in Google Sheets, but it doesn't support traditional programming loop structures directly in its formula language.

However, you can achieve similar results using array formulas, Google Sheets functions that can operate on a range of cells, or through Google Apps Script for more complex operations. 

Using Google Sheets Functions (Array Formulas)

Google Sheets has various functions that can operate on each element of a range automatically, similar to a foreach loop. For example, if you want to add 2 to each number in a range (A1:A10), you can use the ARRAYFORMULA function:

=ARRAYFORMULA(A1:A10 + 2)

This formula will add 2 to each cell in the range A1:A10. Functions like SUMIF, COUNTIF, AVERAGEIF, etc., can also perform operations on each item in a range based on certain conditions.

Using Google Apps Script

For more complex operations or if you need to perform actions that can't be done with a single formula, you can use Google Apps Script. 

Here's a simple example of a foreach loop in Google Apps Script that iterates over each cell in a range and adds 2 to its value:

function addTwoToRange() {

  // Specify your spreadsheet ID here

  var spreadsheetId = 'YOUR_SPREADSHEET_ID_HERE';

  

  // Open the spreadsheet by ID

  var spreadsheet = SpreadsheetApp.openById(spreadsheetId);

  

  // Get the specific sheet by name (replace 'Sheet1' with your sheet's name)

  var sheet = spreadsheet.getSheetByName('Sheet1');

  

  var range = sheet.getRange("A1:A10");

  var values = range.getValues();

  

  for (var i = 0; i < values.length; i++) {

    values[i][0] += 2; // Add 2 to each value

  }

  

  range.setValues(values); // Write the updated values back to the sheet

}

Note: Your spreadsheet ID is the long string in the URL of your Google Sheet. For example, in the URL https://docs.google.com/spreadsheets/d/abc123/edit#gid=0, the ID is abc123.

To use this script:

Step 1: Open Google Apps Script

Go to Extensions > Apps Script.

foreach google sheets

Step 2: Paste the Script

Delete any code in the script editor and paste the above script.

Step 3:  Save the Script

Save the script with a name (e.g. "ForEach Loop").

Step 4: Run the Function

Run the function addTwoToRange from the Apps Script editor.

The execution log should show that the execution has been completed. The changes should be reflected automatically in your spreadsheet.
