excel document 2003

[byronmeyer]

HI,

 

We have a file server with windows 2003 sharing some folders, since the last loss 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 cannot do anything with an empty file"

 

Any ideas?

 

Regards.

Wouldn't this be better asked on a Microsoft forum?

If they're actually zero byte it's too late, there's no data in them to recover.

- If you are able to open the file in Excel, you can try to save the file out into different formats and then re-open them in Excel and try to save them back as Excel workbooks.
-Click on File and then Save As. Choose SYLK (Symbolic Link) from the Save as type list and click Save. Then close the workbook.
-Next, click File and Open again, but this time choose the SYLK file. You may have to choose All Files from the Files of type list to see the SYLK file.
-Once the file is open, click File and then Save As. Now you will choose Microsoft Excel Workbook and click Save. Note that saving using the SYLK format only saves the active worksheet. You will have to save each worksheet individually and repeat this procedure.
-Along with the SLYK format, you can also save the file out using the HTML format. Once saved out, re-open it and try to save it as an Excel workbook. With the HTML format, you don’t need to save each worksheet individually.
One more way is paid, but if nothing helps, it will be useful Recovery Toolbox for Excel **removed**

Did you seriously just register another account to answer your own question?

Oddly, based on locations, it seems not, though the advice above is useless if the file is indeed zero bytes. It won't even have a file header, let alone any data to actually recover.

Wow, that was an elaborate spam technique.

 

Good thing we have rich text so the font gave their copy-paste game away. I guess they were waiting for someone to Google a fix for Excel files and follow this thread, downloading their paid program.
