I was running a workflow with an XLS sheet appender node at the end. I stopped The workflow during the running of the node and I found out that my XLS workbook was totally deleted and corrupted. I would like to recover my data on this Excel sheet. Is there any version saved by Knime? Please help
Does this mean that you were actually writing to the file when you stopped the workflow? In that case, you could try the solution described here: https://support.office.com/en-us/article/Repair-a-corrupted-workbook-153a45f4-6cab-44b1-93ca-801ddcd4ea53
If that doesn't help there is probably not much you can do.
