Which KNIME version are you using? If I got it right you have option Limit memory for column on Advance Settings tab unchecked and still getting this error? How big is file you are trying to read? If file is not confidential can you share it? Additionally you can try File Reader or Simple File Reader to get your data into KNIME.
Thanks for your quick reply.
Unfortunately, I can’t share it - due to senstive information. It is not big! Just 8000 rows and about 20 columns.
I already unchecked the Limit memory for column checkbox.
Saving the csv as xslx and using the Excel Reader workes pretty well.
I see. But that’s odd. Can you check the file size on disk? Glad you found a way with Excel Reader but if one of File Reader nodes work then you don’t have to manually perform file conversion.
