Sort Lines
Sort alphabetical, by length, natural, or reverse.
Use Sort Lines when a pasted list is easier to scan in a consistent order. Paste one item per line, then choose A to Z, Z to A, length ascending, length descending, numeric ascending, or numeric descending. The case-sensitive option affects alphabetical sorting and duplicate-count reporting. The current tool does not perform true natural or version sorting, so item-10 and item-2 are not handled like file names.
Part of: Text Cleanup Tools
How to use
- Paste text with one item per line.
- Choose the sort mode: A to Z, Z to A, length, or numeric.
- Turn case-sensitive sorting on only when capitalization must affect alphabetical order.
- Review the first and last items after sorting.
- Use Remove Duplicate Lines if the stats show duplicates that need cleanup.
Examples
What users are actually trying to do
- ▸ Alphabetize names, tags, labels, keywords, or short lists.
- ▸ Review the shortest or longest items in a word list.
- ▸ Sort simple numeric lines.
- ▸ Prepare a list before visual duplicate checking.
- ▸ Make copied rows easier to scan before importing or editing.
Common mistakes
- ! Expecting true natural sort for item-2 and item-10.
- ! Assuming blank lines are removed automatically.
- ! Using numeric mode on mixed text without checking non-numeric lines.
- ! Expecting trailing spaces to be ignored in length sorting.
- ! Assuming case sensitivity applies to length or numeric modes.
Before you use the result
Word tools can narrow options, clean text, or show patterns, but they do not know the rules of every puzzle, class assignment, publication style, or house dictionary. Check the result against the context where you plan to use it.
For learning, review why a result matched instead of copying the first answer. That keeps the tool useful as practice, not only lookup.
Limitations
- · No true natural/version sort.
- · Blank and whitespace-only lines are preserved.
- · Length mode counts whitespace characters.
- · Numeric mode parses leading numbers and treats non-numeric lines as zero.
- · Alpha sort depends on the browser’s default locale.

Frequently asked questions
› How do I sort lines alphabetically? How-to
Paste one item per line and choose the A to Z mode for alphabetical sorting. The tool reorders the lines and leaves their text contents unchanged. Use Z to A when the reverse alphabetical order is easier for review.
› Is the line sorter case-sensitive? Comparison
The line sorter is case-insensitive by default for alphabetical sorting, with a checkbox for case-sensitive comparisons. That toggle also affects duplicate-count reporting. It does not change length sorting or numeric sorting because those modes compare length or parsed numbers instead of letter case.
› Does Sort Lines remove blank lines? Edge case
No, blank and whitespace-only lines are preserved as sort entries in the current Sort Lines tool. They may cluster near the top or bottom depending on the mode. Remove or edit blank lines manually before sorting if empty rows should not appear in the output.
› How does numeric line sorting work? Definition
Numeric sorting uses the number parsed from the start of each line, and non-numeric lines behave like zero. This is helpful for simple numbered lists but not for mixed labels, versions, or file names. Review outputs that combine words and numbers.
› Does Sort Lines support natural sort for file names? Edge case
No, the current Sort Lines tool does not provide true natural or version-number sorting for mixed labels. Natural sort would place item-2 before item-10 by comparing numeric chunks. That is a high-priority product upgrade, but it is not an existing feature.
› Why is alphabetical order different from another app? Troubleshooting
Alphabetical order can differ because the tool uses browser locale comparison in alpha modes, not one universal collation. Accents, ligatures, punctuation, and case tie-breaks may be handled differently from spreadsheets, code editors, or command-line tools. For ordinary English lists, results should feel familiar.
