Unsupported column type ‘?’. Please remove corresponding column(s) from the input table.

I´m using node concatenate to join two files for further excel writing. Individually I can write on excel, (both of then), when I concatenate I got above error (alwaYS!)

Look carefully at the column types from the tables you’re trying to concatenate. It’s likely that you’re stacking together two different types, like numbers and integers. You could handle this a few different ways - clean up the data prior to concatenation, or doing type conversion afterward.

If you need more help, consider uploading the actual workflow instead of a screenshot.
