Sort Lines Online, A to Z and Beyond
Runs 100% in your browser — your text never leaves this page, and nothing is uploaded or stored.
This sort lines online tool sorts A to Z or Z to A, by length or numerically, with natural number order — item 2 before item 10 — and optional dedupe. Use it to sort lines alphabetically — this alphabetizer tool puts names, keywords and inventories in natural order, so item 2 correctly comes before item 10, with optional dedupe in the same pass.
How to Use Sort Lines Online
- Paste your list into the box — or press Load sample to sort the example basket of items.
- Choose the ordering: alphabetical, reverse alphabetical, by length, or numeric low-to-high or high-to-low.
- Leave Case sensitive off for normal lists; tick it when capitals must sort separately.
- Tick Remove duplicates after sorting if repeated lines should be dropped in the same pass.
- Read the sorted list in the result box — the note confirms how many lines were sorted.
About this tool
Sorting a list by hand invites mistakes; sorting it here takes a second. The alphabetical mode uses natural ordering — it understands the numbers inside text, so “file 2” sorts before “file 10” instead of after it, which is where a plain character-by-character sort would wrongly put it. Six orderings cover the real jobs. A→Z and Z→A for names, keywords and inventories. Shortest-first and longest-first for headline variants, titles and posts you are comparing by size. And two numeric modes for value-led lists — with one honest detail: numeric sorting reads the number each line starts with, treating a line that starts with no number as zero, which is exactly right for exports whose values lead the line. By default the sort ignores case, so “Apple” and “apple” are treated as the same word and capitalised entries do not all jump to the top. Tick Case sensitive for code and data where case is meaningful. The dedupe option removes repeated lines after sorting, judged by the same case rule you chose — and completely empty lines are dropped before the sort even begins. Your original stays untouched in its box while the sorted version appears in the result box, ready to copy or download. Everything runs in your browser — private lists, customer names and unpublished keywords never leave your device.Worked example
Here is the sample list that comes with the tool, sorted with the default settings (alphabetical A→Z, case ignored): You pastezebra Apple mango 10 items 2 items Banana kiwi 100 itemsYou get
2 items 10 items 100 items Apple Banana kiwi mango zebraThe note reads “8 lines sorted.” Two things to spot: the numbered lines come first and in natural order — 2 before 10 before 100, not the 10, 100, 2 a plain character sort would give — and the fruit follows case-insensitively, so capitalised “Apple” and “Banana” take their proper alphabetical places instead of jumping ahead of the lowercase words.
