The problem it solves

Your team manages data in a spreadsheet because it's easy, but the actual database other tools rely on quickly falls out of date. Keeping the two in sync by hand means constantly copying, checking, and deleting rows to make sure nothing was missed.

Who it fits

Teams who manage data in spreadsheets but need it reliably reflected in a database other systems depend on.

How it works

  1. On a set schedule, the system pulls the latest records from Google Sheets and Supabase
  2. It compares both sets of data using a shared ID
  3. New rows in the spreadsheet are created in Supabase
  4. Changed rows are updated, and rows removed from the sheet are deleted from Supabase
What you get

Records that match your sheet automatically

Your Supabase database quietly mirrors whatever you keep in Google Sheets, staying in sync without anyone updating both.

What you get

An up-to-date Supabase table that always mirrors your Google Sheet, with no manual copying.

What you need

A Google Sheets account and a Supabase project.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
