We are experiencing a strange issue with excel protection. We have 2 excel password protected base templates. We use Aspose.cells to open this template and do some manipulations and finally save it as new file.We are not calling any Protect/Unprotect methods during this process. But strangely one of the work book is getting unprotected automatically (Other template is fine and protection still exists). The password got removed somehow for one workbook.
Please help us in this regard.
