This may be possible but if so I’m missing it. Please add the ability to be able to have 2 way sync to Google Docs. I know about import and export, but it would be great to be able to have the Sync ability if possible.
You can use one of the integrator services that work with Grist to set up two-way sync between Sheets and Grist. It would require two integrations; one that sends updates from Sheets to Grist and another that sends updates from Grist to Sheets.
Improving integrations is an ongoing project. You can view it on our roadmap and add comments and suggestions!
