How can I secure my Excel file with a password?

To secure an Excel file with a password, the user can follow a straightforward process. First, they should open the Excel file that they wish to protect. Next, they will need to navigate to the "File" tab located in the top-left corner of the window. From there, they should select "Info" and then look for the "Protect Workbook" option. Upon clicking this, they will see a variety of security options, and the user can choose "Encrypt with Password." This will prompt the user to enter a password of their choice. It is essential to remember this password, as losing it may result in the inability to access the file. After entering the password, the user should confirm it and then click "OK." The file is now encrypted and can only be accessed by those who know the password. For additional information, it may be helpful to visit the official Microsoft Excel webpage.
