About Sort Text Lines
Sorting lines of text is a common task for developers, writers, and data analysts. Whether you are alphabetizing a list of names, sorting imports in code, ordering numbers correctly (so "10" comes after "9"), or arranging URLs by length, manual sorting is tedious and error-prone. This tool sorts text lines in many ways: alphabetically (A→Z or Z→A), numerically (correct number ordering), by line length (shortest first), or in reverse. It handles real-world edge cases: case-insensitivity, natural sort (file2 < file10), deduplication, and removing empty lines. All processing happens in your browser — your text is never uploaded.
How It Works
- Paste your text (one item per line) into the input box.
- Choose a sort method: A→Z, Z→A, numeric, by length, or reverse.
- Optionally enable: ignore case, natural sort, remove empty lines, deduplicate.
- See the sorted result instantly. Copy or download as .txt.
✨ Key Features

- ✓Numeric sort (correctly orders 2 before 10)
- ✓Natural sort (file2 before file10)
- ✓Sort by line length (shortest or longest first)
- ✓Reverse current order
- ✓Ignore case option
- ✓Remove empty lines option
- ✓Remove duplicate lines option
- ✓Live sorting as you type
- ✓Copy or download result
- ✓100% client-side — no data sent to any server
🎯 Common Use Cases
- →Alphabetizing names, emails, or contact lists
- →Sorting numeric lists correctly (2, 10, 100 not 10, 100, 2)
- →Sorting CSS properties or JS imports
- →Organizing URLs by length for design purposes
- →Preparing data for reports and presentations
- →Sorting product SKUs or codes
- →Cleaning up log entries before analysis
- →Sorting keywords for SEO research
💡 Advanced Tips & Pro Insights
- ▸For mixed text and numbers (file1, file2, file10), use "Natural sort" — it correctly orders numbers embedded in text. Without it, "file10" comes before "file2" (lexical order).
- ▸Numeric sort is different from natural sort: numeric sort works best when lines are pure numbers (e.g., "5", "20", "100").
- ▸Combine "Ignore case" + "Deduplicate" for the cleanest result when cleaning up email lists.
- ▸For sorting imports in code: alphabetical A→Z with "Ignore case" is the JavaScript/TypeScript convention.
- ▸For descending numbers (highest first), use "Numeric sort" + "Reverse".
Frequently Asked Questions
Is this line sorter free?▾
Yes, this text line sorter is completely free with no signup, email, or usage limits.
Is my data safe?▾
Yes, 100% safe. All sorting happens in your browser. Your text is never uploaded to any server.
What is natural sort?▾
Natural sort orders text with embedded numbers the way humans expect. "file2" comes before "file10" (not after, as in lexical sort). Useful for sorting file names, versions, and SKUs.
What is the difference between alphabetical and numeric sort?▾
Alphabetical sort compares characters (so "10" < "9" because "1" < "9"). Numeric sort parses numbers and compares them numerically (so 9 < 10). Use numeric sort when lines are pure numbers.
What does "Sort by length" do?▾
Sorts lines by their length (number of characters). Useful for design (shortest items first) or for finding the longest/shortest entries in a list.
What is "Ignore case"?▾
When enabled, "Apple" and "apple" sort together as if they were the same case. Useful for sorting real-world lists where capitalization is inconsistent.
Can I sort numbers from highest to lowest?▾
Yes. Choose "Numeric" sort, then enable "Reverse" (or choose Z→A with numeric mode). This gives descending order.
Does it handle very large lists?▾
Yes, up to browser memory limits. Sorting 100,000+ lines is typically instant on modern browsers.
