What Is a Sort & Dedupe Lines Tool?
Lists of lines — names, URLs, log entries, CSV columns — often need sorting, deduplicating or tidying before use. Doing that by hand is tedious and error-prone. This free Sort & Dedupe Lines tool orders your lines alphabetically, numerically, by length or randomly, removes duplicates and empty lines, and trims whitespace — all instantly in your browser.
This tool treats your text as a list — one item per line — and reorders or tidies the whole list at once. It can sort lines alphabetically or numerically, ascending or descending, strip out duplicate lines, reverse or randomly shuffle the order, and trim away stray spacing. What would take careful manual cutting and pasting becomes a single, reliable operation on hundreds or thousands of lines.
How to Sort
- Paste your lines.
- Choose a sort order and toggle dedupe / trim / remove empty.
- Copy the cleaned-up result.
Applications
- Developers and sysadmins tidying config entries, log lines, hostnames or import lists before using them.
- Data analysts removing duplicate rows from a column pasted out of a spreadsheet or database export.
- Marketers cleaning email lists, keyword lists or tag sets so every entry appears once, in order.
- Anyone organising a long list — names, links, to-dos or references — into alphabetical or numerical order.
How the Sorting Works
Your text is split into individual lines at each line break. Alphabetical sorting compares lines using a locale-aware comparison so accented and international characters order naturally, while numerical sorting reads the leading number of each line and orders by value, so 2 comes before 10 instead of after it. Deduplication keeps the first occurrence of each unique line and discards the rest.
Options let you control case sensitivity, choose ascending or descending order, and trim surrounding whitespace before comparing, so "Apple" and " apple " can be treated as the same entry when you want. Shuffling uses a random permutation, handy for sampling or randomising an order.
Why Use It
- Multiple sort modes including numeric and by length.
- Deduplicate, trim and drop empty lines in one pass.
- Runs in your browser — private and free.
Sorting Happens Locally
Your text is sorted using a sorting algorithm that runs in your browser as JavaScript. The lines you enter and the sorted result remain on your device — nothing is sent to our servers.
