An AI agent that can update your Google Sheets

Read values, update cells, append rows — on exactly the spreadsheets you expose and no others. Each sheet is granted read-only or read & write, per agent profile; the rest of your Drive doesn't exist as far as the agent knows.

FGAC × Google Sheets — setup walkthrough

How it works

  1. Connect FGAC (three-step setup) — all spreadsheets start denied.
  2. Pick sheets with the Google Picker on an agent profile. Each starts read-only; flip individual sheets to read & write when the agent should update them.
  3. Ask away: “What's in the Budget tab?”, “Append today's totals to the tracking sheet”, “Update the status column for closed items”.

Things people build on it

  • Logging daily metrics or expenses as appended rows
  • Sweeping data out of Gmail (receipts, signups) into a tracking sheet
  • A reporting agent that reads three sheets but can write to only one
  • Keeping a CRM-ish sheet updated from conversation notes

If an agent tries a sheet you haven't exposed — or a write on a read-only sheet — it's denied, and you get a one-click link to grant exactly that access if you want it.
