Common issues

If you're having trouble installing or running a Cellstronaut add-on in Google Sheets, you're at the right place. Below are the most common issues and how to solve them.

Installation or usage issue: Multiple Google accounts

Problem: If you click Install and see messages like Bad Request: Error 400 or Too many redirects, it usually means you're signed in to multiple Google accounts. Google Workspace add-ons don't support multi-login, or being logged into multiple Google accounts at once. This also affects how the add-ons function after the installation.

Fix: Sign out from all your Google accounts and sign back in with just the account where you want to install the add-on.

Selection limit: Too many active ranges

For some reasons, Google Sheets can't select many individual cells at once. If you select too many non-contiguous cells/ranges, the browser tab may freeze or crash with an unresponsive page message.

Add-on actions fail with a network error when many ranges are selected

Problem: If you have 80 or more non-contiguous ranges selected in the spreadsheet, any add-on action that works with your data — such as selecting results, expanding rows, or adding formulas — may fail with a network error.

This is a known Google Apps Script bug. When too many ranges are selected, Google's infrastructure rejects the add-on's requests before they are even processed.

Fix: Click on any single cell in the spreadsheet to clear the selection, then run the action.

Blank or unresponsive add-on window

Problem: If the add-on shows a blank screen or some features aren't working, required resources may be blocked by your browser, antivirus software, ad blockers, or your company security policies. This may also happen due to a poor internet connection, or when the page is not refreshed for an extended period of time. All these prevent the add-on from loading correctly and functioning as expected.

Possible fixes:

• Make sure your internet connection is stable.
• Refresh the page and try again.
• Disable browser extensions that block external scripts, like ad blockers. Or whitelist the domains from the list below.
• Check your antivirus/firewall settings. Make sure to whitelist the domains from the list below.
• If you're on a corporate network, ask your IT team to allow these domains.

Domains to whitelist:

• select-special-t1.cellstronaut.com
• select-special-t2.cellstronaut.com
• table-total-t1.cellstronaut.com
• table-total-t2.cellstronaut.com
• *.googleusercontent.com
• docs.google.com

Only Help menu item appears in Extensions

Problem: Sometimes the only item you see in the Extensions add-on menu is Help. This may happen when:

• Your spreadsheet contains a large number of custom formulas.
• You have too many add-ons installed in your account.
• Other add-ons or custom formula recalculations are running in other open spreadsheets. See Limitations for Google Services.
• Your internet connection is slow or unstable.

Possible fixes:

• Close other spreadsheets and reload the current one.
• Uninstall unused add-ons.
• Reduce formula load if possible.
