Sort Lines
Sort any block of text line by line — alphabetically, numerically, or by length. Numeric sorting uses real number values, not string order.

What does this tool do?
The Sort Lines tool takes a block of text and reorders the lines according to the sort mode you choose. It is useful for sorting lists, cleaning up code, organising data, and more.
Sort modes
- A → Z — alphabetical ascending (locale-aware).
- Z → A — alphabetical descending.
- Numeric ↑ — ascending by numeric value. Lines that are not numbers fall back to alphabetical order.
- Numeric ↓ — descending by numeric value.
- Short → Long — ascending by character count.
- Long → Short — descending by character count.
Numeric sorting example
Input: 10 / 2 / 30 / 4
Numeric ascending → 2 / 4 / 10 / 30 (not 10 / 2 / 30 / 4 as alphabetical would give).
Options
- Case-sensitive — uppercase letters sort before lowercase when enabled.
- Remove duplicates — keep only the first occurrence of each unique line.
- Remove empty lines — blank lines are excluded from the output.
How to use
- Choose a sort mode from the buttons at the top.
- Paste your text into the input — one item per line.
- The sorted output appears immediately below.
- Click Copy to copy the result.

Frequently Asked Questions
What happens to empty lines during sorting?
By default, empty lines are preserved but moved to the bottom of the sorted list. Check 'Remove empty lines' if you prefer to exclude them entirely.
How does numeric sorting differ from alphabetical sorting?
Alphabetical sorting checks character-by-character ('10' comes before '2'). Numeric sorting parses the true numerical value of each line so that 2 comes before 10.
Can I sort lines by character length?
Yes. Select 'Short → Long' to sort from shortest to longest line, or 'Long → Short' for reverse length ordering.
Is my text sent to a server?
No. All line sorting algorithms execute locally in your browser using client-side JavaScript. No data is sent across the network.
