How to Lock Cells in Smartsheet

Use this interactive demo to learn how to lock columns and cells in Smartsheet's Grid View.

Quick summary

Locking cells in Smartsheet prevents unauthorized edits by restricting changes to a specific column directly from the Grid View. This four-step process uses the built-in Column Menu to apply a column-level lock in seconds.


Steps

  1. In Smartsheet's Grid View, locate the cells you want to protect and click the column header above them.
  2. Click the corresponding Column Menu button that appears for the selected column.
  3. Select Lock Column from the dropdown list of column options.
  4. The selected column and all cells beneath it are now locked and protected from edits.

📌 Why this matters

Locking columns in Smartsheet is essential for maintaining data integrity across collaborative projects, preventing accidental or unauthorized edits to critical fields. The Lock Column feature gives sheet owners and admins granular control over which data can be modified, reducing errors in shared workflows. This is especially valuable for teams managing project timelines, budgets, or compliance-sensitive data where consistency is non-negotiable. By restricting edits at the column level, Smartsheet helps organizations enforce data governance without removing collaborator access to the rest of the sheet.
