How to Change the Password in Excel
Microsoft Excel provides users with the ability to create lists and spreadsheets of information. These spreadsheets sometimes contain private and sensitive information. Users may add a password on the Excel file so the information is not available to anyone who obtains the file unless they enter the proper password. You may also change the password as needed.
Open the Excel spreadsheet you want to edit. If the file already has a password configured, enter the password and click "OK."
Click "File" in the main menu toolbar and select "Save As." In the window that opens, click the "Tools" button to open a dialog box for advanced settings.
Click "General Options." In the text box labeled "Password to modify," enter a new password for your Excel file. Press "OK."
Click "Save" to save your new password settings. The Excel file saves to the hard drive and the password is modified.
