SP2013 corrupted .xlsx file - Need to recover

Question

I need to recover a corrupted .xlsx file in SP2013 document library. The document cannot be downloaded(or)copied(or)restored back to previous versions.It shows Cobalt Error was thrown while restoring it to previous versions. Tried exporting the document through designer/opening it from excel also fails. Other .xlsx files in same doc library renders fine.Any other possible ways to recover the corrupted one.

Hi Nanddeep Nachan Thanks a lot for the response. I dont have the local copy of file. The file was only available in the doc lib with version history enabled. Hence  unluckily no local copy available. Any other ways we can recover ?
