Catch Apps Script mistakes before you run. Autocomplete, type diagnostics, hover docs, and quick fixes in the Apps Script editor.

myFunction adds diagnostics and targeted quick fixes directly to the Google Apps Script editor at script.google.com. CHECK YOUR CODE WHILE YOU EDIT • Find misspelled API methods, missing arguments, and invalid parameter shapes. • Spot repeated spreadsheet reads inside loops and review suggested batching fixes. • Catch malformed email addresses, including invalid recipients inside comma-separated CC lists. • Review diagnostics across the files in your open project. • Infer parameter types from function calls and review the suggested JSDoc annotations. REVIEW THE CHANGE, THEN APPLY IT Open a quick-fix preview to compare the original code with the proposed correction. Choose whether to apply the change to your open editor. myFunction does not run your scripts or create deployments. FREE ACCESS AND PRO Try diagnostics in one ten-minute window without an account.
