Replace the parts in <angle brackets>.What comes back
- The census tract (the FFIEC-style 11-digit code)

Every plan, including Free. On Free, InstaMaps uses your one custom connector; Google Drive, Gmail and Google Calendar are directory connectors and don't count against it.

Before you start
Reading Google SheetsShare the sheet with InstaMaps, or set it to "anyone with the link can view". InstaMaps reads it straight from Google, so a sheet of thousands of rows is one call, and nothing passes through the chat.
Writing to Google SheetsInstaMaps writes to the sheet itself: share it with the address the answer gives you, as Editor. It adds new dated columns or a new tab, and never overwrites a cell.
Good to know
- US facts for US addresses, England facts for English ones. Each answer says which official dataset it came from.
- The connector is free: 5,000 tool calls a day per person, and a whole sheet read by link counts as one call.
