The Script Editor in Google Sheets is the environment where you write, edit, and manage Google Apps Script projects. It provides the tools needed to create automated workflows, custom functions, and integrations for your spreadsheets.

1. Accessing the Script Editor

Step 1: Open your Google Sheet
Step 2: Click Extensions in the menu
Step 3: Select Apps Script

A new tab opens with the Script Editor interface where you can write and run your scripts.

Code Editor – The main area to write and edit scripts using JavaScript syntax
File Menu – Create new scripts, HTML files, or manage project files
Toolbar – Run scripts, debug, save, and deploy your project

3. Writing Your First Script

A simple example to display a message in Google Sheets:

function showMessage() {
  SpreadsheetApp.getActiveSpreadsheet().toast("Hello! Script Editor is ready.");
}

• SpreadsheetApp.getActiveSpreadsheet() accesses the active spreadsheet
