TSV (Tab-Separated Values) is a plain text format where each row is a line and columns within each row are separated by tab characters. It is similar to CSV but uses tabs instead of commas, avoiding the need to escape commas in data values.

How do I extract specific columns from TSV data?

Select 'Extract columns', enter the column numbers you want (e.g. 1,3,5), and click Run. Column numbers start from 1.
