@molenich ,

See the following C#.NET sample code for your needs. I use Aspose.Cells APIs to accomplish the task. The code snippets opens an encrypted XLSX file (here you got to specify the correct password), then removes the password before re-saving the file. When you open the output XLSX file, MS Excel won't prompt for password as the file would not be protected/encrypted anymore. e.g. Sample code:

string password = "abcd";
Aspose.Cells.LoadOptions loadOptions = new Aspose.Cells.LoadOptions();
loadOptions.Password = password;
var wb = new Aspose.Cells.Workbook("e:\\test2\\PasswordProtected_file1.xlsx", loadOptions);
wb.Settings.Password = null;//remove the password.
wb.Save("e:\\test2\\out1.xlsx");
