I would like to get the custom attributes of a protected excel workbook.
But seems the following line
Aspose.Cells.FileFormatInfo fft = Aspose.Cells.FileFormatUtil.DetectFileFormat(ms);
This doesn’t give any info about the custom attributes and
Workbook workbook = new Workbook(, options) needs password.
We add the custom attribute while generating the spreadsheet and while trying to open the sheet using the app, we use the custom attribute to retrieve the password from database. But we’re stuck with the aspose api to get the excel file custom attribute.
Is there any aspose solution available? the custom attributes are readable from the explorer window without password. So expecting password to read the attribute doesn’t sound correct.
