how to recover a corrupted excel file ?
Posted on 2015-02-18
We have a file server with windows 2003 sharing some folders, since the last lost of energy the server restarted but we have noticed that some excel files are now corrupted, we got the following message:
"Excel cannot open the file myfile.xls because the file format or file extension is not valid"
We have tried to open and repair the file, but always appears an empty file.
Also, We tried "Excel repair toolbox" application but this tool indicates the following:
"All bytes in the file myfile.xls are equal zero. Program can not do anything with an empty file"
