If you want to protect key data from being changed or deleted by others who are shared to your sheet, you can lock columns and rows. Data contained in cells in locked rows or columns cannot be edited. Similarly, cells in newly inserted rows won't be editable in locked columns.

Another way to protect your data is to use the right sharing permissions when you share your sheet (for example, share a sheet to someone with Viewer permissions rather than Editor permissions if you don't want them to be able to make changes).

You can create rules that lock rows automatically when specific conditions are met. More information on this is available in Automate Your Work with Alerts and Actions.

Here are some things to keep in mind about locking columns and rows:

  • You must have Owner or Admin permissions to a sheet to lock or unlock columns and rows
  • Others with Owner or Admin permissions will be able to edit and delete locked columns and rows
  • Editors will be able to see locked columns/rows, but they won't be able to delete or edit the data in them. The same rule applies to anyone working from an Update Request or Published sheet
  • A lock can be applied to any column or row, with the exception of the Attachment and Comment columns which cannot be locked

Lock a Column or Row

  • To lock a column, right-click the column header and click Lock Column.
    Lock Column Menu
  • To lock a row, right-click a row number and click Lock Row.

A lock icon will appear in the column or row headers to indicate that a column or row has been locked.

IMPORTANT: Locking a column doesn't prevent a person with editor sharing permissions from deleting or moving rows. It prevents them from editing or deleting any data in that column.

  1. Right-click on row's number and select Unlock Row. (Or, click the lock icon in the row’s Lock column.)
