class DocumentApp method .getActiveDocument()

DocumentApp is the Apps Script service.

.getActiveDocument() is the method name you will see after a dot in your code.

What it does

Returns the Google Doc the user currently has open.

Why it's used

  • Edit the Google Doc the user has open right now.
  • Bound doc scripts use this like getActiveSpreadsheet for sheets.

Common errors

  • Forgetting parentheses on getActiveDocument. Write DocumentApp.getActiveDocument(), not DocumentApp.getActiveDocument or getActiveDocument by itself.
  • Skipping dots between chained calls. Each step needs a dot, like DocumentApp.getActiveDocument().getBody().getActiveDocument().
  • Adding spaces where they do not belong. Write DocumentApp.getActiveDocument(), not DocumentApp .getActiveDocument(), DocumentApp.getActiveDocument (), or DocumentApp . getActiveDocument().
  • Wrong capitalization. Use DocumentApp and getActiveDocument, not documentapp or getactivedocument.
