Alphabetical Sorter
Sort a list of lines A→Z or Z→A. Case-sensitive, case-insensitive, natural or by length.
About Alphabetical Sorter
The Alphabetical Sorter reorders a list of lines A→Z or Z→A, with case-sensitive, case-insensitive, natural (so "file2" comes before "file10") and by-length modes. Optional trimming and de-duplication clean up messy lists in the same pass.
Each input line is treated as one item, which preserves spaces inside names and phrases. Natural ordering is particularly useful for filenames and identifiers containing numbers, while length ordering quickly surfaces the shortest or longest entries.
Sorting runs client-side, so private lists — names, emails, candidates — stay on your device. Trimming can remove accidental spaces around each line before comparison, and de-duplication can reduce a copied list to unique entries in the same workflow.
Spreadsheets can sort columns, but pasting a one-off list into this tool is often faster when you only need a clean order and a unique set of lines. Empty lines are easy to spot after a sort because they cluster at the start or end depending on direction, making it obvious when a paste introduced blank rows.
Because comparison options are explicit, you can deliberately choose whether "Beta" and "beta" collide as duplicates or remain separate catalog entries. That control matters for title lists, product SKUs and any export where capitalization carries meaning.
How Alphabetical Sorter works in practice
- 1Paste your list into the input box, one item per line.
- 2Pick the sort key: alphabetical, natural or length.
- 3Pick the direction: ascending or descending.
- 4Optionally toggle "Trim lines" and "Remove duplicates".
- 5Copy the sorted output or apply it back to the input.
Jobs this tool is built for
- Alphabetize a copied list of attendees, products, cities or bibliography entries.
- Put filenames such as chapter2 and chapter10 into human-friendly numeric order.
- Remove duplicate email addresses after trimming spaces from a pasted export.
- Sort headlines, labels or keywords by length to check interface and layout constraints.
- Prepare a glossary or tag list in A–Z order before publishing documentation.
- Order inventory SKUs that mix letters and numbers so humans can scan them without spreadsheet formulas.
What you can do here
- Case-sensitive and case-insensitive modes
- Natural sort (numbers inside strings sort numerically)
- Sort by length
- Deduplicate and trim options
- Handles thousands of lines
- One-pass cleanup for pasted exports
Limits and honest caveats
- Natural sort only affects embedded numbers; pure letter strings still follow alphabetical comparison.
- Deduplication depends on your case and trim settings — preview carefully before discarding variants you meant to keep.
- Sorting runs entirely in your browser, so private name or email lists are not uploaded.
Common questions about Alphabetical Sorter
What is natural sort?
It sorts numbers inside strings the way humans expect — "file2" before "file10", not after.
Does it handle accented characters?
Yes — sorting uses localeCompare, so é sorts near e.
What does case-sensitive sorting change?
It treats uppercase and lowercase forms as distinct during comparison. Use case-insensitive mode when Apple and apple should be grouped together.
Does removing duplicates ignore capitalization?
Duplicate behavior follows the tool’s comparison options. Review the result when your list contains variants such as Name, name and trailing spaces.
Will blank lines be sorted?
Yes. Empty lines are treated as items and typically gather at one end of the list, which helps you notice accidental blank rows from a paste.
Can I sort a comma-separated list without newlines?
Put each item on its own line first. The sorter treats the whole line as one entry, so commas inside a line stay part of that item.
