Google Sheets Update Cell When Another Cell Changes? Mastering Automation

by

As a Google Sheets user, you’re likely familiar with the power of conditional formatting, formulas, and automation. One of the most common scenarios in Google Sheets is updating a cell when another cell changes. This feature is incredibly useful for tracking changes, calculating values, and even automating workflows. In this article, we’ll explore the various ways to update a cell when another cell changes in Google Sheets.

Why Update a Cell When Another Cell Changes?

Updating a cell when another cell changes can be incredibly useful in a wide range of scenarios. For example, you might want to:

  • Track changes: When a value in one cell changes, you might want to update a log or a history of changes.
  • Calculate values: When a value in one cell changes, you might want to recalculate a formula or a calculation.
  • Automate workflows: When a value in one cell changes, you might want to trigger an automated process or send a notification.

These scenarios are just a few examples of the many ways you can use the “update cell when another cell changes” feature in Google Sheets.

Using Google Sheets’ Built-in Functions

Google Sheets has several built-in functions that allow you to update a cell when another cell changes. One of the most common functions is the ON CHANGE function.

The ON CHANGE function is a simple and powerful way to update a cell when another cell changes. Here’s an example of how to use it:

=IF(A1="changed", "Value updated", "")

In this example, the formula checks if the value in cell A1 has changed. If it has, the formula returns the text “Value updated”. If it hasn’t, the formula returns an empty string.

Using the ON CHANGE Function with Conditional Formatting

You can also use the ON CHANGE function with conditional formatting to highlight changes in a cell. Here’s an example: (See Also: Google Sheets How to Go to Next Line? Quick Tips)

=IF(A1="changed", "Value updated", "")

In this example, the formula checks if the value in cell A1 has changed. If it has, the formula returns the text “Value updated”. If it hasn’t, the formula returns an empty string. You can then use this formula as the basis for a conditional formatting rule to highlight the cell.

Using the ON CHANGE Function with Scripts

You can also use the ON CHANGE function with scripts to automate workflows or send notifications. Here’s an example:

function onEdit(e) {
  var sheet = e.source.getActiveSheet();
  var range = e.range;
  if (sheet.getName() == "Sheet1" && range.getColumn() == 1) {
    var value = range.getValue();
    if (value == "changed") {
      // Code to run when the value changes
    }
  }
}

In this example, the script checks if the value in cell A1 has changed. If it has, the script runs a block of code. You can customize this code to automate a workflow or send a notification.

Using Google Apps Script

Google Apps Script is a powerful tool that allows you to automate workflows and customize Google Sheets. You can use Google Apps Script to update a cell when another cell changes.

  1. Open your Google Sheet.

  1. Open the script editor and click on the “Triggers” button.
  2. Click on the “Create trigger” button.
  3. Choose the trigger type (e.g. “On edit”).
  4. Choose the script to run.
  5. Set the trigger options (e.g. “Run on edit” and “Run every 1 minute”).
  6. Click on the “Save” button.
