XLSX is a spreadsheet file created by Microsoft Excel or exported using OpenOffice Calc or Apple Numbers. Since XLSX represents a list of worksheets with tables all the data is stored in cells. Worksheets can also contain graphics such as images and charts. Typically we use spreadsheets for calculations and data aggregation. When your spreadsheet file is not protected anyone who has access to a file can open it. In case your XLSX spreadsheet contains sensitive or private information you can limit access to it by setting a password.
Password Protect is a free secure online web application that enables you to protect XLSX spreadsheets. You can easily add a password to XLSX file within a couple of clicks and download a protected file.
To password protect XLSX spreadsheets we're using AES (Advanced Encryption Standard). This encryption method provides high protection level against brute-force attacks that are used by attackers to decrypt a protected file.
To secure XLSX spreadsheets using Password Protect application upload your file, type the password, click protect button, and download the protected file. The download link will be available for 24 hours. While we automatically remove your files from our servers we also enable you to remove the files manually. After you removed files manually the download link won’t work anymore.
