FAQ About Sort Lines

What is 'numeric' sort?

Numeric sort parses each line as a number (if possible) and sorts by value. Lines that can't be parsed are sorted alphabetically.

Does case-insensitive sort work with non-English characters?

Yes. The tool uses Unicode case folding, which handles accented characters correctly.

Can I sort by multiple criteria?

This tool sorts by one criterion at a time. For multi-criteria sorting, sort multiple times in reverse priority order.
