The effective way to find out if a Calc spreadsheet is recoverable is to try the demo version of Recovery for Calc on it. Visit the Demo page for a free copy of the demo.
Product specifications with lists of items recovered and not recovered is available at the Product Information page.
Note: Always backup your original corrupted Calc spreadsheet before proceeding with any recovery activity!
What limitations does the demo version of Recovery for Calc have?
The demo version recovers a limited number of cells. The remaining cells will contain "demo" text instead of real data. Full version of Recovery for Calc will recover the demo-limited rows as well.
No additional tables or records are recovered by commercial version of Recovery for Calc if not present in demo output.
I have tried the demo. How do I decide whether to purchase the full version of Recovery for Calc?
Evaluating the results of demo recovery can help in making the decision.
What are the differences between product licenses?
Details of current licensing scheme are described at the Licensing page.
Why do results of recovery contain less data than the original Calc spreadsheet?
This is normal. The damaged parts of your Calc spreadsheet will convert to zero size on output. The other common reason of file size decrease is when some of features of the original spreadsheet are not supported and therefore absent from the recovered spreadsheet.
Demo-recovered spreadsheet is smaller because it mostly consists of demo placeholders than actual data.
Running Recovery for Calc from command line (through Windows Start -> Run menu).
If your license type is Enterprise or Service, you can run Recovery for Calc from command line and use these calls in your batch files. Standard version does not support command line. The format for command line call is:
