Frequently Asked Questions

How does alphabetical sorting work?▾
Lines are compared character by character using Unicode code point values. By default, uppercase letters sort before lowercase (A < a). Enable case-insensitive mode to ignore capitalization differences.
What does numeric sort do?▾
Numeric sort parses the leading number from each line and sorts by that value instead of alphabetically. This means '2' sorts before '10' (unlike alphabetical sorting where '10' comes before '2').
Can I sort in reverse order?▾
Yes. Select 'Descending (Z-A)' from the Order dropdown to sort lines from Z to A (or highest to lowest for numeric sort).
How are blank lines and lines with leading whitespace handled?▾
Blank lines are sorted to the top in ascending order since empty strings come before any character. Lines with leading whitespace are sorted based on the space or tab characters, which come before letters in Unicode order. Trim whitespace first if you want to sort purely by text content.
