About this tool

Selects columns by name or position and emits a narrower file, quoting preserved. Inverting the selection drops the named columns instead, which is the quicker way to remove one column from many.

Questions

Can I reorder columns?
Yes — output follows the order you list them in, so naming them in a different order rearranges the file.
