XLS Sheet Appender Error

I've started getting the following error with the XLS Sheet Appender Node:

"Execute failed: Your InputStream was neither an OLE2 stream, nor an OOXML stream".

Any ideas? I can see nothing wrong with the input table.

Cheers,

Steve.

Sounds like this is more of a problem with the file that you want to append to. Could you please provide an example file and workflow? Can you read in the XLS file with the XLS Reader?

Cheers,

OK, I've realised that the XL file got corrupted, deleting the file and re-running the Append Sheet nodes solved the problem.

Cheers,

Steve.
