Google Sheets
Google's cloud spreadsheet — the most common lightweight database used in low-code automation.
Definition
Google Sheets is Google Workspace's spreadsheet app, frequently used as a quick database for automation: append rows from webhooks, read rows on a schedule, drive lookups inside a workflow. The Sheets API has rate limits per project (e.g. 60 read requests per minute per user) that surface as quota errors in high-volume scenarios.
