Microsoft Excel is the world's most popular spreadsheet software used in finance, statistics, science, and other fields. People use Excel spreadsheets to manage data, analyze information, create reports, and perform other tasks.
Microsoft Excel allows protecting a file from being opened by unauthorized users. The only person who knows the password can view or modify your file. This protection cannot fully secure the file from brute-force password attacks, so remember to set complex passwords created by password generators.
Microsoft Excel supports several levels of protection. You can set the password required to view the document (open the file). You can also set a permission password to restrict specific actions such as editing a spreadsheet, commenting, or tracking changes.
This free online application based on the GroupDocs API removes the password protection of Microsoft Excel files. You have to specify the password to unlock the file. We value your privacy, so the file and the password are visible to you only. You can download the unprotected file to open it. The application works on any device, including smartphones.Video tutorial
