Questions
How do I remove duplicate lines from text?
Paste your text into the input field and enable the deduplication option. The tool will remove all repeated lines while preserving the first occurrence of each unique line.
Can I sort lines numerically instead of alphabetically?
Yes, the tool supports multiple sort modes including alphabetical, numerical, and by line length. Numerical sorting correctly orders numbers by value so that 10 comes after 9 rather than after 1.
Can I sort lines in reverse order?
Yes, toggle the reverse option to sort lines in descending order. This works with alphabetical, numerical, and length-based sorting modes.
Is the line sorting case-sensitive?
By default, sorting is case-sensitive (uppercase letters sort before lowercase). You can enable case-insensitive sorting to treat "Apple" and "apple" as equal for ordering purposes.
