Find missing data in a Google Sheet with your AI agent

Your agent finds your sheet by name, reads its rows and lists every row with a missing email address, so you know what to fix before you send anything. It only reads; nothing in the sheet changes.

How does the agent do it?

The agent makes 2 calls through ClawLink. You do not pick the tools: the agent finds them by searching ClawLink, reads their input schema and runs them.

How often does this work on ClawLink?

We do not publish a sample run for this job: its output is somebody's own Google Sheets. Instead, here is how the same tools performed for every ClawLink user from 2026-09-03 to 2026-10-03. A call counts as failed only when it reached Google Sheets and came back with an error.

How do you write the prompt?

  • Name the sheet and the column. "The Leads sheet, column Email" removes guessing.
  • Ask for row numbers. So you can jump to each row in the sheet.
  • Check more than one field. "Missing email or phone" works in the same run.

What can go wrong?

  • Header row. If the first row is not a header, say so, or the agent skips a real row.
  • Several tabs. A spreadsheet can have many tabs. Name the tab.
  • Large sheets. Tens of thousands of rows need reading in parts. Ask the agent to page through.
