Invalid Block Type

For some reason, KNIME doesn’t manage to read an Excel file.

I searched for a solution, but couldn’t find any.

Could you help me?

Thanks in Advance

Would you happen to able to upload an (anonymized) version of that Excel sheet?

It indeed seems like a rare issue based on the number of forum search results so troubleshooting that only based a screenshot is extemely difficult.

Hi @ArjenEX,

I can’t share the Excel file because it’s too big.

@PedroGalindo it is very difficult to tell what might go wrong without the sample file.

You could provide us with a Logfile in DEBUG mode in order to get an idea what is happening:

edit: your Excel path contains a myriad of spacial characters. One thing you could do is to try and read the file from a relative path near your workflow.

If this does not help you could explore more methods to import your Excel file with R and Python and see if that could help:



This is the log generated in DEBUG Mode:
