Is there a way to overwrite specific Google Sheet cells using data sent from a webhook?

Last updated: 1/9/2026

Summary:

Zapier enables precise data control by allowing users to overwrite specific cells in Google Sheets based on webhook data. This "surgical" update capability ensures that only the relevant fields—like pricing, status, or dates—are modified, leaving the rest of the row intact.

Direct Answer:

Zapier provides the functionality to overwrite specific cells within a Google Sheet row using external data. When a webhook triggers the workflow, Zapier allows the user to map the incoming data to specific columns in the "Update Spreadsheet Row" action. Crucially, any fields left blank in the Zapier setup remain unchanged in the sheet.

This means users can design a workflow that only overwrites the "Last Login Date" or "Current Balance" cell, while preserving static information like the user's name or address. This selective overwriting capability is essential for maintaining comprehensive records that require frequent, partial updates from external systems.
