Recover corrupted file

Hi folks,

I have attached a file which throws this error when someone tries to open it "Excel cannot open the file 'a.xlsx' because the file format or file extension is not valid. Verify that the file has not been corurpted and that the file extension matches the format of the file." I will appreciate if any one can get me data from this file or suggest some tools to recover this file. Thanks in advance.

i can open it as a .doc if you change the file extension other than that i tried opening it with open office calc and it still opened as a doc. looks mostly gibberish tho

any hopes to recover data ??

open as a doc. have a look and see if the data is what you need it may be extractable from that

If this product is the same as Pareto FleCure, I recommend anyone read the reviews at http://download.cnet.com/FileCure/30...-75000187.html before downloading this product. The consensus seems to be it's worse than awful.

If it's a different product, there are no independent reviews anywhere, and there is no information about the company on the website. I would stay a mile away from this.

i looked at it and all it seems to do is

This software identifies the file type of troublesome files

well since we know this is xlsx what would be the point?
maybe if you had an odd adf2345dy.tmp and wanted to find out its original file type, even then the reviews seem to point out it's lack of usefulness
