How to prevent editing?

In this article we will learn how to prevent editing in Excel file.

Select File>Info>Protect workbook>Encrypt with password:

encrypt with password

Enter password twice:

Sheet is protected with password now:

Make as final (read only)

Similarly we can make the workbook read only using similar options:

Select File>Info>Protect workbook>Make as Final

mark as final

Similarly we can make choose the Protect Workbook Structure option also.

The final way you can add protection at the workbook level is by protecting the workbook's structure.

This type of protection prevents people who don't have the password from making changes at the workbook level, which means they won't be able to add, remove, rename, or move worksheets.
