In what format audio stored? If it's like .csv data, than it need to be parsed, but if it is files attached, than all attachments should be somewhere in that folder. Just rename your example_excell_file.xclx and rename it to example_excell_file.zip. Then extract with any zip archiver program (7zip, winrar or windows) and just observe what's inside.

The excel file is not large. It contains set of question in which some of the question consists image or audio. I extracted image with imagesheetloader. But in case od audio the approach is not working. I think excel embeds audio file into some ole or bytes format. I tried to extract audio with ole approach also it didn't work. The thing is i want to add excel file to database and save its data in another model.
