Add-on Not Loading? Reset Permissions and Fix a Blank Sidebar

Fix a blank sidebar or repeated sign-in prompts in Text To Table Converter by resetting Google third-party access, reauthorizing the add-on, and checking your account session.

If the Text To Table Converter sidebar opens blank, keeps asking you to sign in, or a tool will not respond, reset the add-on's Google permissions first. This usually clears an incomplete or outdated authorization.

Reset Google Third-Party Permissions#

The quickest fix for a permissions approval problem is to remove Text To Table Converter from your Google Account's third-party access list, then authorize it again.

  1. Open Google Account third-party connections.
  2. Find and select Text To Table Converter.
  3. Click Remove access and confirm.
  4. Return to Google Docs™, Google Slides™, Google Sheets™, or Google Forms™.
  5. Open the add-on from Extensions > Text To Table Converter > ⚡ Launch Sidebar.
  6. When Google shows the authorization screen, allow all permissions requested by the add-on.

This gives the add-on a fresh authorization instead of reusing a declined or partially approved permission.

Signed In to Several Google Accounts?#

Being signed in to multiple Google accounts at once in the same browser can cause a blank sidebar or an endless sign-in loop. Google Workspace™ add-ons can end up running under a different account than the one that owns your document.

The fix: stay signed in with the Google account that owns the document. Sign out of extra accounts, or use one browser profile per account.

Quick test: Open a private/incognito window, sign in with only the account that owns your document, and open the add-on again.

Is It a Word, Excel, or PowerPoint File?#

The add-on does not run in Word, Excel, or PowerPoint files that you open in Google Docs™, Sheets™, or Slides™ in compatibility mode (files ending in .docx, .xlsx, or .pptx). Convert the file first: click File > Save as Google Docs (or Save as Google Sheets / Save as Google Slides), then open the add-on in the new file.

View-Only Access Shows "Editor Permission Required"#

If you only have view or comment access to a file, the sidebar shows Editor Permission Required. The add-on needs edit access to change a file. Ask the owner for editor access, or make your own copy with File > Make a copy and use the add-on there.

The File Access Prompt Fails#

Some tools ask you to approve access to the current file in a Google prompt. If that prompt fails or closes right away, allow third-party cookies for Google in your browser settings, then try again. Browsers that block third-party cookies can stop the authorization from completing.

Icon or Menu Missing Right After Install#

After a fresh install, it can take a moment for the add-on icon and menu entries to appear. Refresh your browser tab (F5 or Cmd+R), then open the add-on again.

Still Stuck?#
