Quick Links
-
I have a new free web service and a piece of freeware for recovering data from corrupt Excel 2007 files available here: http://www.saveofficedata.com/. The freeware is the Corrupt xlsx2csv mentioned below, which uses a different mode of coding then the service. If the web service, Corrupt xlsx2csv doesn't work, you have Excel 97-2003 files or you need format recovery try ExcelFix.

More Detail
The freeware and the free methods here may work about 20% of the time, and are not particularly impressive compared to commercial varieties, but then again, if free works, you just saved some money.
-
Step by Step Procedures for Recovering Excel Data - believe it or not there are 4 separate ones here. The steps try to be comprehensive and include some references to the commercial recovery software available.
-
Free Excel Compatible Spreadsheets and Spreadsheet Viewers - sometimes corrupt Excel files will open in other spreadsheets or spreadsheet viewers. In addition to Open Office, please see other free Office Suites on my page devoted to that. There should be 3 more. For the viewers, it's a long process, but the software should allow copying cells, which can then be pasted into a new spreadsheet in Excel proper.
-
Misc. Excel Recovery Freeware - These are admittedly nowhere near the caliber of the for pay corrupt excel recovery programs.
-
Text Extractors - Excel files are binary, but I think the actual data remains in text format in the file. A text extractor would then be able to pull it out for you in an albeit unformatted file.

Please note: Honestly the commercial software and services is the route you will sometimes have to take to recover your data. Generally, it's a lot easier to find free programs for file repair for non-Microsoft products than Microsoft ones. You can explore them by following the links to the left.
On those occasions that you try the freeware and it doesn't work, the software in these pages will appear not be worth the time and effort you put in and this can be frustrating. I try to point out at the top of each page, what I see is the likelihood that and difficulty with which freeware can recover your data.
The Google Adsense Ads displayed on the pages should lead you to the standard commercial software and services available for the problem you are having. You can also try the commercial links by clicking on the Navigation Bar by the file type name on the left. It's also here.
To see if the program works before buying, always be sure to try the demos of commercial software first. Also the difference in prices for software that does the same thing, for instance recovering PowerPoint Presentations, can be a large range like with PowerPoint case $50 - 299. If possible, try several software solutions before buying. For services, be sure there is a no data, no fee guarantee, and a recovered file preview available.
