I am downloading some excel from my AUT and whenever i try to open it throws this error-

when i use apache poi with this file it doesn’t work and throws “Your file appears not to be a valid OLE2 document” can someone help me here . Thanks

Probably the file you downloaded is not an Excel file, but something else. I guess, it is an HTML that contains some error message. For example, “access prohibited” or “Internal Server Error”.

Just download and save it into a local file, and manually open it with some text editor. You would see what the file acutally is.
