[sunweiconfidence]

hi,

i use below code to encrypt excel's specific sheet, but not work, for Workbook, i can encrypt successfully:

        string excelFile = Path.Combine(currentDirectory, "test.xlsx");
        string encryptedfile = Path.Combine(currentDirectory, "encryptedtest.xlsx");
        Workbook workbook = new Workbook(excelFile);
        workbook.Worksheets[0].Protect(ProtectionType.All, "1234", "");
        // Save the excel file
        workbook.Save(encryptedfile);

so what should i use to let it work, i use aspost.cells version as below: Aspose.Cells: 20.11.0 OS: Windows10

Could you please share "test.xlsx" and output Excel file here, we will check it soon. Also provide your expected file (you can create the expected encrypted file (containing your expected protected sheet in tact) in MS Excel manually).

Moreover, we have dedicated forums to get support in quick time and we encourage you to post your queries or issue in respective forum.

@sunweiconfidence ,

Just an update. We did have a temporary glitch due to SSL issue at our end. However, it's fixed now. Please give it a try again. Thanks.
