About the Delimited Column Deleter
The Delimited Column Deleter helps you remove specific columns from delimited text like CSV or TSV. Specify the columns you want to remove and the tool processes your data while keeping the structure of the remaining columns intact.
Pick a delimiter, list the column numbers to remove, and paste in your data — the tool applies that removal consistently across every line, making it easy to clean up a wide dataset or strip out a sensitive column before sharing it.
