Apps Script: Import Data from External Google Sheets

In a previous article, we introduced the concept of Google Apps Script and its potential. This article takes the exploration further by diving into one of the capabilities that Apps Script offers, how to import data from an external Google Sheet. This process can simplify data aggregation, reporting, and analysis, ensuring that your information is up-to-date and centralized.

The script typically involves identifying the source sheet, selecting the data to be imported, and pasting it into the destination sheet. You can also include error handling and data formatting as needed.
    • By using methods from the Google Class Spreadsheet, you can construct code that pulls that data that you want from whatever sheet you want.
  4. Testing and Execution
    • Once you’ve developed the script, save it, and run it directly from the Apps Script editor. Be prepared to authorize the script to access your Google Sheets. Your script is associated with the Google Sheet you’re working in and can always be accessed from the extensions menu or at
