Best Practices for Protecting Cells in Excel

Here are some best practices to keep in mind while protecting cells in Excel:

Use passwords to protect your worksheet

Excel offers password protection for worksheets, which provides an additional layer of security beyond protecting individual cells. To password-protect your file, you can click the ‘Protect workbook’ option under the Review tab. It’s important to choose a strong password that includes a combination of uppercase and lowercase letters, numbers, and special characters.

Protect all cells before sharing your document

Before sharing your workbook with anyone, make sure to protect all cells with sensitive data to prevent any unauthorized viewing or editing. Even if some of the cells do not contain critical information, protect them as well to maintain consistency throughout your worksheet.

Make a backup of your file

It’s always a good idea to make a backup of your file before you start protecting the cells. If anything goes wrong during the process, you can easily recover your original document.

Add comments to cells

If you allow some users to edit certain cells, you can make their job easier by adding comments to those cells. These comments serve as a guide to what should be entered in the cell and any other useful information that may come in handy.
