JMP Excel File Import - Can I ignore columns in the Excel file?

BSwid — Fri, 19 Oct 2018 18:06:10 GMT

Either in the import wizard or in the import script (data source script) can I write script that ignores certain columns so that it is not imported from the source file to the JMP file?

No, and you wouldn't want to. It may be unintuitive but it will be faster to just import the entire .csv file and then delete the extra columns via dt << Delect Columns(ListOfColumns). CSV importers are heavily optimized for reading the data, they aren't built for data clean up which would come at the cost of too much overhead.

Thank you. So in summary, import all, then add to the script the delete columns syntax. Could you please point me ot the syntax in JSL to delete multiple columns?
