Why teams start here
Sheets is familiar, shareable and supported by most automation platforms. It works well as a visible log of leads, requests or tasks while a process is still being designed.
How automations use it
Platforms read and write rows through the Google Sheets API. Keep a fixed header row and stable column names, because many integrations map fields by header.
Limits to plan for
The API enforces request quotas, and a spreadsheet offers no unique constraints or row locking. Two automations writing to the same sheet at once can create duplicates or overwrite each other.
When you need guaranteed uniqueness, high volume or concurrent writers, move the data to a database or a CRM and keep Sheets as a report.
