The XLSM files may be protected 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.

This free online application based on the GroupDocs API removes the password protection of the XLSM 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.
