Line Sorter

What is Line Sorter?

Line Sorter sorts, shuffles, deduplicates, and cleans up text on a line-by-line basis. It supports alphabetical, numerical, and length-based sorting in both ascending and descending order. The tool can remove blank lines, trim whitespace, strip duplicates, and reverse the line order. Operations can be chained as a pipeline for complex text transformations.

Developers organizing import statements, data analysts cleaning extracted lists, and content managers deduplicating keyword lists. The tool runs entirely in your browser — your data never leaves your device.

How to Use Line Sorter

1. Paste your text with one item per line into the input editor
2. Select the sort mode — alphabetical, numerical, or by line length
3. Choose ascending or descending order from the direction toggle
4. Enable additional operations — remove duplicates, trim whitespace, or remove blank lines
5. Copy the processed output or download it as a cleaned text file

Common Use Cases

• Alphabetically sorting imports or require statements in source code files
• Deduplicating lists of email addresses, URLs, or keywords extracted from various sources
• Randomizing a list of quiz questions or survey options for unbiased ordering
• Sorting CSV rows by a text column without opening a spreadsheet application
• Cleaning up copy-pasted lists by removing blank lines and trimming whitespace simultaneously

Pro Tips

• Use numerical sort when your lines start with numbers — alphabetical sort would place 10 before 2 because it compares character by character
• Combine remove duplicates with case-insensitive sorting to eliminate entries like React and react that differ only in capitalization
• The shuffle mode uses the Fisher-Yates algorithm for true random ordering — useful for creating unbiased test data or randomized lists
