Line Sorter
Sort lines of text alphabetically, numerically, by length, or in reverse order.
What Is a Line Sorter?
A Line Sorter is a simple yet powerful text utility that organises a list of lines into a specified order instantly. Whether you have a messy list of names, URLs, file paths, numbers, or any other line-separated data, the Line Sorter rearranges every line according to the rule you choose — alphabetically, numerically, by character length, or simply reversed.
Unlike sorting inside a spreadsheet or code editor, this tool works entirely in the browser: paste your text, pick a mode, and your sorted list is ready to copy in seconds with zero installation required.
How to Use the Line Sorter
- Step 1 – Paste your text into the Input Text area (one item per line).
- Step 2 – Choose a Sort Mode: A→Z, Z→A, Numeric Ascending/Descending, Shortest/Longest First, or Reverse Order.
- Step 3 – Set options such as case-insensitive sorting, duplicate removal, empty line filtering, and whitespace trimming.
- Step 4 – Click "Sort Lines" to process your text. The result appears instantly in the Output panel.
- Step 5 – Copy the output with the Copy button and paste it wherever you need it.
The stats bar below the output tells you how many lines were processed, how many duplicates were removed, and how many empty lines were filtered out so you always have full visibility over what changed.
Common Use Cases
- Sorting a list of names or contacts alphabetically before importing into a CRM.
- Ordering a list of URLs, file paths, or domain names for easier review.
- Deduplicating and sorting keyword lists for SEO or ad campaigns.
- Numerically sorting log lines, version numbers, or IDs exported from a database.
- Arranging to-do items or task lists by description length for quick scanning.
- Reversing a chronological list of entries to see newest items first.
- Cleaning up a messy CSV column pasted as plain text.
Frequently Asked Questions
Does the Line Sorter keep my data private?
Yes — all processing happens entirely in your browser using JavaScript. No text is ever sent to a server, so your data stays completely private.
What does "case-insensitive sort" mean?
When this option is enabled, uppercase and lowercase letters are treated as equal during sorting. For example, "apple", "Apple", and "APPLE" will be grouped together rather than split by capitalisation.
How does Numeric sorting work?
Numeric mode extracts the leading number from each line and sorts by its value. Lines that don't start with a number are treated as having a value of 0 (for ascending) or placed after all numbered lines. This is ideal for sorting version numbers, IDs, or ranked lists.
What counts as a "duplicate" line?
Two lines are considered duplicates if they are identical after applying your current options. If "Case-insensitive" is on, "Hello" and "hello" count as duplicates. If "Trim whitespace" is on, " hello " and "hello" also count as duplicates.
Is there a limit to how many lines I can sort?
There is no hard limit imposed by the tool — it relies entirely on your browser's memory. In practice it handles tens of thousands of lines without any issues.
Can I sort lines by length and also remove duplicates at the same time?
Absolutely. All options (case-insensitive, remove duplicates, ignore empty lines, trim whitespace) work independently of the chosen sort mode, so you can combine them freely in any combination.
