Why Sort Lines?
Sorted text is dramatically easier to work with — you can spot duplicates at a glance, find specific entries quickly, and ensure consistency. Whether it's a list of names, a dataset, CSS properties, or import statements, sorting brings instant order to chaos.
Sorting Modes
- Alphabetical (A → Z): Standard ascending order. "Apple" before "Banana".
- Reverse alphabetical (Z → A): Descending order.
- By line length (shortest first): Useful for inspecting items by size.
- By line length (longest first): Find the most complex entries at the top.
- Numeric sort: Sorts numbers correctly — so 2 comes before 10 (unlike alphabetical where "10" comes before "2").
- Shuffle (random): Randomize the order of lines.
Remove Duplicates While Sorting
Our Sort Lines tool includes a Remove Duplicates option. Combined with sorting, it's the fastest way to deduplicate any list without writing code:
1Paste your list (even if it has hundreds of duplicates).
2Check "Remove Duplicates" and choose "A → Z".
3Copy the clean, sorted, deduplicated list instantly.
Common Use Cases
- Keyword lists: Sort and deduplicate SEO keyword lists for cleaner spreadsheets.
- CSS properties: Sort CSS declarations alphabetically for easier maintenance.
- Import statements: Many style guides require sorted imports in Python, JavaScript, etc.
- Name lists: Alphabetize a list of attendees, students, or contacts.
- Domain lists: Sort and deduplicate firewall allowlists or blocklists.
💡 Case Sensitivity: By default, uppercase letters sort before lowercase. Enable "Case-insensitive sort" for alphabetical sorting that treats "Apple" and "apple" as the same value.
FAQ
What about empty lines in my list?
Enable "Remove empty lines" before sorting to clean up any blank lines that would otherwise float to the top or bottom of your sorted output.
