Grid Tools Troubleshooting Guide

Browser extensions that inject into third-party web apps are sensitive to page load order, cached content, and host app updates. Grid Tools can stop working or behave unexpectedly when Smartsheet updates its interface, when browser caches serve stale pages, or when a permission was not granted correctly during install.

Without Grid Tools

The daily workaround

Toolbar disappears after Smartsheet update
Smartsheet DOM changes can cause injected toolbar elements to fail to render until Grid Tools is updated to match.
Tools grayed out for no clear reason
Stale cached Smartsheet pages or a missed activation step cause tools to appear in the toolbar but remain non-functional.
Hard reload fixes it but users don't know that
Most Grid Tools injection issues resolve with a hard reload, but users do not know to try this before reporting a problem.
Permissions silently revoked
Some browsers revoke extension permissions after updates or policy changes, causing Grid Tools to load but fail to inject.

Frequently asked questions

The Grid Tools toolbar was working and now it's gone. What happened?

Smartsheet regularly updates its web interface. A DOM change can break toolbar injection until Grid Tools releases an update. Check for a pending extension update first.

I installed Grid Tools but the toolbar never appeared. What should I try first?

Do a hard reload of the Smartsheet tab (Ctrl+Shift+R on Windows, Cmd+Shift+R on Mac) after confirming the extension is enabled in your browser's extension manager.

Why are all my Grid Tools buttons grayed out even though I'm signed in?

This usually means Grid Tools loaded but could not confirm your entitlement. Sign out and back in from the extension popup, then reload Smartsheet.

Does Grid Tools break when Smartsheet releases updates?

Occasionally. When Smartsheet changes its interface significantly, Grid Tools may require an update. Grid Tools releases patches quickly when this happens, and the extension updates automatically.
