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.
