Error Load Data before trying to read

[nei]

I am getting this warning message ans after that a fatal error. It does not show much information where is the issue. There is a way to have debug messages to see what is going on during this process?

hello @nei

i didn't have this error since a long time. If i remember well, it can happen when trying to read an unknown worksheet. Did you customize the xlsx structure?

Hi @jmleroux

That was right. I received the file customised by someone else. I had to copy all the data in chunks to a new file and it seems the error disappeared but it took me about 10 hours to go through the file since it was huge :)

It would be very useful if we could add some information on debug level which would help understand where is the issue.

Totally agree, i just created #20 to keep it in the backlog.
