I want to ask if Aspose cells can differentiate encrypted xlsx from encrypted pptx and encrypted docx?
My Aspose version: 22.214.171.124. C#
My use case: user submits encrypted file which can be pptx, xlsx and docx. I want to detect the correct filetype, which is docx or xlsx or pptx. User dont submit the file’s password.
My code is
FileFormatInfo info = FileFormatUtil.DetectFileFormat(inputFile); // pptx and docx are detected as info.LoadFormat = xlsx.
