Sort a List

Free list sorter tool. Sort lists alphabetically or numerically in ascending or descending order. Remove duplicates optionally.

Please ensure your list values are separated by a line break.

Free Online List Sorter

Paste any list and sort it alphabetically or numerically — ascending or descending — with an optional duplicate-removal step. Everything runs in your browser; no sign-up needed and your data stays private.

How to Use

  1. Paste your list into the text area (one item per line).
  2. Choose Ascending (A to Z) or Descending (Z to A) order.
  3. Select Text for alphabetical sorting or Number for numerical sorting.
  4. Optionally check Remove duplicates to deduplicate in the same step.
  5. Click Sort List to get your sorted results instantly.

Text vs. Number Sorting

Choosing the right sort type matters. Text sorting compares values character by character, which means "10" sorts before "9" alphabetically. Number sorting treats each value as a real number, so 9 correctly sorts before 10. Use Text for names, cities, and alphanumeric codes; use Number for prices, quantities, IDs, and any other purely numeric data.

Common Uses

  • Mailing lists — sort email addresses or contact names A–Z before importing into a CRM
  • Product data — sort SKUs or product names alphabetically for catalog reviews
  • Numeric data — sort prices, scores, or IDs in ascending or descending order
  • Dropdown options — sort options alphabetically before adding them to a form or select field
  • Keyword lists — organize SEO keywords or tags alphabetically for easier review

Sort and Deduplicate in One Step

Checking Remove duplicates strips repeated values before sorting, so you get a clean, unique, ordered list in a single click — without needing to run a separate deduplication step first.

Frequently Asked Questions

How do I sort a list alphabetically?
Paste your list (one item per line) into the tool. Select 'Alphabetical' as the sort type, choose ascending (A-Z) or descending (Z-A) order, and click Sort. The tool rearranges your items in the specified order while preserving the one-item-per-line format.
What's the difference between alphabetical and numerical sorting?
Alphabetical sorting treats items as text strings (so '10' comes before '2' because '1' < '2'). Numerical sorting treats items as numbers (so 2 comes before 10). Use numerical sorting for lists containing only numbers, alphabetical for text or mixed content.
Can I remove duplicates while sorting?
Yes. Check the 'Remove duplicates' option before sorting, and the tool will eliminate repeated values while sorting. This is useful for creating sorted unique lists from messy data with duplicates. The first occurrence is kept; subsequent duplicates are removed.
Is case sensitivity applied in sorting?
By default, the tool uses case-sensitive sorting where uppercase letters come before lowercase (A-Z then a-z). This follows standard Unicode collation rules. If you need case-insensitive results, consider converting case before or after sorting.
What can I use this sorting tool for?
Common uses: alphabetizing name lists, sorting product SKUs, organizing email addresses, ordering numbered lists, preparing data for binary search, cleaning messy data, creating indexes, and standardizing lists for comparison or deduplication with other datasets.
