Assuming you’re using the latest version of KNIME, in the configuration of the Excel Reader node you can input multiple files, and it will concatenate them based on the existing columns. You can also specify a range of rows and columns to read, and which row contain column headings.
It is my ROW ID. I like to delete this ROW ID and Set the Row0 as my ROW ID.
This doesn’t make sense to me. How can a row be a row ID?
