Create a custom Google Apps Script to automate a specific action on Google Sheet.
Example:ooo appsscript I would like Google Sheets to display a confirmation prompt whenever a user clicks on any cell in column B, asking them to confirm or cancel the change to the cell’s value. Result:To achieve the desired functionality in Google Sheets, we’ll create a Google Apps Script that triggers a confirmation prompt whenever a user clicks on any cell in column B. The script will ask the user to confirm or cancel the change to the cell’s value. Here’s how you can implement this:
---
### Step 1: Open the Google Apps Script Editor
1. Open your Google Sheet.
2. Go to Extensions > Apps Script.
3. Delete any existing code in the script editor.
---
### Step 2: Write the Script
Copy and paste the following code into the script editor:
javascript function onEdit(e) { // Define the column to monitor (Column B = 2) const COLUMN_TO_MONITOR = 2; // Get the edited range and sheet const range = e.range; const sheet = range.getSheet(); // Check if the edited cell is in Column B if (range.getColumn() === COLUMN_TO_MONITOR) { // Get the new value entered by the user const newValue = e.value; // Display a confirmation prompt const ui = SpreadsheetApp.getUi(); const response = ui.prompt( 'Confirmation Required', `Are you sure you want to change the value to "${newValue}"?`, ui.ButtonSet.YES_NO ); // If the user cancels, revert the change if (response.getSelectedButton() !== ui.Button.YES) { range.setValue(e.oldValue); // Revert to the old value } } }
---
### Step 3: Save the Script
1. Click the Save button (or press Ctrl + S
).
2. Name your project (e.g., "Confirmation Prompt for Column B").
---
### Step 4: Set Up the Trigger
1. In the Apps Script editor, click on the clock icon on the left sidebar to open the Triggers page.
2. Click Add Trigger.
3. Set the following options:
- Choose which function to run: onEdit
- Choose which deployment should run: Head
- Select event source: From spreadsheet
- Select event type: On edit
4. Click Save.
---
### Step 5: Test the Script
1. Go back to your Google Sheet.
2. Click on any cell in Column B and enter a new value.
3. A confirmation prompt will appear. If you click No, the cell’s value will revert to its previous state.

### Documentation for Users
#### How to Use the Script
1. Open the Google Sheet where you want to implement the confirmation prompt.
2. Go to Extensions > Apps Script.
3. Copy and paste the provided script into the editor.
4. Save the script and set up the trigger as described above.
5. The script will now prompt for confirmation whenever a user edits a cell in Column B.
#### Notes
- The script only monitors Column B. If you want to monitor a different column, change the value of COLUMN_TO_MONITOR
in the script.
- The script uses the onEdit
trigger, which runs automatically when a user edits a cell.
- If the user cancels the change, the cell’s value will revert to its previous state.
