Troubleshooting the Sheetgo Add-on for Google Sheets
The Sheetgo Add-on lets you import, combine, and export data between Google Sheets, Excel, and CSV files, and schedule those automations to run on their own. When something goes wrong, it's usually one of a handful of things: the add-on won't open, an automation won't run, the file picker misbehaves, or Google asks you to reauthorize.
Most of these are quick to fix. Start with the quick fixes below. If that doesn't do it, jump to the section that matches what you're seeing.
First, the quick fixes
These clear up the majority of problems:
Reload and reopen. Refresh the spreadsheet tab, then open the add-on again from Extensions → Sheetgo. A lot of glitches are just a stale session.
Use one Google account at a time. If you're signed in to several Google accounts in the same browser, sign out of the others, or open your spreadsheet in an Incognito/private window with just the account you want.
Allow cookies for Google. The add-on and the file picker require Google cookies. Safari and private windows often block them, allow cookies (or turn off tracking prevention) for
google.comanddocs.google.com.Pause browser extensions. Ad blockers and privacy tools can interfere. Turn them off for this site, or try an Incognito window with extensions disabled.
Reauthorize if you're asked to. If you see a "Reconnect with Google" or "Reauthorize" prompt, complete it (details below).
The add-on won't open (blank panel, endless spinner, or it's not in the menu)
You open it from Extensions → Sheetgo, and the side panel stays blank, shows loading dots that never finish, or the add-on isn't listed at all.
What to try:
Reload the spreadsheet and reopen the add-on. This fixes most blank or stuck panels.
Check you're in one Google account. When more than one account is signed in, the add-on can load under the wrong account. Use a single account or an Incognito window.
Allow cookies for Google and reload (see quick fixes).
Pause extensions and try again.
If it's not in the menu: make sure the add-on is installed (from the Google Workspace Marketplace) and refresh the spreadsheet. You can review installed add-ons under Extensions → Add-ons → Manage add-ons.
If it asks for permission: grant it (see the next section).
You're asked to authorize or reconnect (and scheduled automations stopped)
You see an "Authorize" or "Reconnect with Google" prompt when you open the add-on, a red "Reauthorize required" on one of your automations, or scheduled automations that quietly stopped running.
Why it happens: the first time you use the add-on you grant it permission to work with your files. Later, when we update what the add-on can access, Google asks you to approve the change. Until you do, automations pause, and scheduled ones won't run.
How to fix it:
Open the add-on and click Reconnect with Google (or Reauthorize), then approve the permissions.
Scheduled automations resume on their next scheduled run after you reauthorize.
On a work or school (Google Workspace) account, your administrator may need to approve the add-on before you can.
An automation won't run, or fails partway through
The message you see usually points to the cause:
"Automation timed out at 6 minutes." Google limits how long a free add-on can run at once (about 6 minutes). Large sources or many steps can hit that. Try a smaller range or fewer rows, split the work into smaller automations, or upgrade to Sheetgo Automations Pro, which runs on Sheetgo's own platform and is not subject to Google's 6-minute cap.
"Daily Google quota reached." Google limits the number of scripts that can run per day across all your automations. Wait until the next day, or upgrade to run without the daily quota.
"Source too large to read" or "File size limit reached." The file is bigger than the free plan allows. Use a smaller file, or upgrade.
"Destination too large to update" or "Couldn't finish writing to destination." The destination is too large or has hit a limit. Reduce the data you're writing, or upgrade.
An access error on a source or destination. If a file was moved, deleted, or its sharing changed, the automation can't reach it anymore. Open the automation and re-select the file.
A plan limit ("Automation limit reached", "Source limit reached", "Filter condition limit reached"). The free plan allows up to 10 automations, 10 sources per automation, and 10 filter conditions. Remove some, or upgrade for more.
It still fails, or says "Execution timed out … the automation may be too complex." Try running it again. If it keeps failing, simplify the automation (fewer sources or steps) or contact support.
The file picker won't open, or shows the wrong files
When you add a source or destination, you choose a file with the Google Drive picker. If it won't open, opens under the wrong Google account, or looks empty, the quick fixes are: use a single Google account, allow cookies for docs.google.com, and pause ad blockers or privacy extensions.
See Why the file picker won't open (or shows the wrong files) for step-by-step fixes for each symptom, including: picker won't open, wrong account, empty picker, "didn't load", "couldn't connect", and "selection wasn't received".
The imported data looks wrong (missing columns, empty, or the wrong rows)
This is usually a configuration or source-change issue rather than an error:
Open the automation and check the source's cell range and whether the first row is set as the header row.
If the source file changed (columns renamed or removed), the automation may no longer find them. Re-open the source step and review the columns.
Run the automation again after adjusting.
Scheduled automations aren't running
Reauthorize. After an update, scheduled automations pause until you reconnect (see the authorization section above). This is the most common reason.
Check file access. If a source or destination was moved, deleted, or unshared, the run will fail. Re-select the file.
Daily Google quota. Heavy usage across your automations can hit Google's daily limit.
Check the schedule is still on in the automation's settings.
Free plan limits (quick reference)
The free add-on runs on Google's platform, so it inherits Google's limits, and Sheetgo adds a few of its own:
Up to 10 automations
Up to 10 sources per automation
Up to 10 filter conditions
File size around 1 MB for uploads
Runs limited to about 6 minutes each (Google's limit)
Daily Google script quotas
Sheetgo Automations Pro runs on Sheetgo's own web platform rather than Google's, so it isn't bound by the 6-minute cap or daily quotas, and it raises the other limits.
