🧐 FAQ

Is it case-sensitive?

Yes. "Apple" and "apple" are treated as distinct lines. If you need a case-insensitive scrub, run your text through a Case Converter first to normalize it.

Does it work with CSVs?

Yes. The tool processes text line-by-line, making it perfect for removing identical rows from CSV exports.
