Locking cells in Excel can be useful in a variety of situations. For example:

  • You have a spreadsheet with formulas that you don’t want others to accidentally change.
  • You’re sharing a spreadsheet with others and want to make sure they can only edit certain cells.
  • You’re using a template that has certain cells locked so that users don’t accidentally overwrite important data.

In these situations, locking cells can help prevent errors, protect your data, and save you time and effort in the long run.

  5. Click “OK” to close the Format Cells dialog box.
  6. Protect the worksheet. Click on the “Review” tab in the ribbon, and then click “Protect Sheet”. In the Protect Sheet dialog box, you can set a password and choose which actions users are allowed to take, such as selecting locked cells, formatting cells, or inserting/deleting rows and columns.

Once you’ve locked your cells and protected your worksheet, other users will be able to view the locked cells but won’t be able to edit or change them without the password.
