Enrich Google Sheets rows via any REST API in rate-limited batches

How it works • Reads all rows from a Google Sheet • Splits them into configurable batches (default: 5 rows per batch) • Calls any external REST API once per row (GET or POST, Header Auth) • Waits 1 second between batches to stay within API rate limits • Routes responses: writes enriched data back to the sheet on success, logs errors on failure • Loops through all batches until the full sheet is processed • Want more REST API workflows?
