Excel is a powerful tool for organizing and analyzing data, but sometimes you may want to prevent others from modifying the contents of a worksheet. Whether you’re sharing sensitive information or simply want to maintain the integrity of your data, making an Excel worksheet read-only can be a crucial step. In this article, we’ll guide you through the process of how to make an Excel worksheet read-only, ensuring that your data remains secure and unaltered.

2. Click on the “Review” tab in the ribbon at the top of the screen.
3. In the “Changes” group, click on “Protect Sheet.”
