# Text Line Sorter & Duplicate Remover

Sort text lines alphabetically, by length, numerically, reversed, or shuffled. Optional trim and dedupe while you sort. Runs in your browser, no signup.

**Use this tool:** [Text Line Sorter & Duplicate Remover](https://findutils.com/text/text-line-sorter/)

## Programmatic access

- REST id `line-sort`: POST https://api.findutils.com/api/tools/line-sort/execute (reference: https://findutils.com/api/line-sort/)
- MCP tool `line_sort` on https://mcp.findutils.com (reference: https://findutils.com/mcp/line-sort/)

## Why use Text Line Sorter?

Quickly organize lists, clean up data exports, and remove redundant entries. Perfect for processing CSV data, cleaning up email lists, organizing code imports, or preparing data for analysis. All processing happens in your browser for privacy.

## Pro Tips

- Use the 'Use as Input' button to chain operations: first remove duplicates, then sort alphabetically in a second pass.
- Enable 'Case Sensitive' when sorting code tokens or identifiers where uppercase and lowercase have distinct meaning.
- Choose 'Numeric' sort for lists that mix text and numbers, like 'Item 2' and 'Item 10', so they order correctly instead of lexicographically.
- Combine 'Trim Whitespace' with 'Remove Duplicates' to catch lines that only differ by leading or trailing spaces.
- Use 'Random Shuffle' to randomize a list of names for raffles, seating charts, or randomized testing order.

## Frequently Asked Questions

### How does duplicate removal work?

When 'Remove Duplicates' is enabled, only the first occurrence of each line is kept. With 'Case Sensitive' off, 'Apple' and 'apple' are considered duplicates and only the first one is kept.

### What does numeric sorting do?

Numeric sorting extracts the first number found in each line and sorts by that value. Lines like 'Item 10' will sort after 'Item 2' correctly, unlike alphabetical sorting where '10' comes before '2'.

### Can I sort by multiple criteria?

Currently you can sort by one criterion at a time. However, you can use the 'Use as Input' button to apply multiple transformations sequentially - first remove duplicates, then sort alphabetically.

### Is my data secure?

Yes, all text processing happens entirely in your browser. Your data never leaves your device or gets sent to any server. You can safely process sensitive information.

### What is the maximum amount of text I can sort?

There is no hard limit. The tool runs in your browser, so performance depends on your device. Most modern devices handle tens of thousands of lines without any noticeable delay.

### How does sorting by length work?

Length sorting counts the total number of characters in each line and orders them from shortest to longest or longest to shortest. This is useful for finding outlier entries in lists or organizing CSS properties by declaration length.

### Can I use this tool to alphabetize a list?

Yes. Select the 'A to Z' sort order to alphabetize any list. The tool handles accented characters and mixed-case text. Disable 'Case Sensitive' if you want uppercase and lowercase letters treated equally during sorting.

### Does random shuffle produce truly random results?

The shuffle uses a Fisher-Yates algorithm powered by your browser's built-in random number generator. It is suitable for everyday randomization tasks like raffles, classroom ordering, or playlist shuffling, though not for cryptographic purposes.

### Can I undo a sort operation?

There is no dedicated undo button, but the original text remains in the input panel until you clear it. You can always re-paste your original text or adjust the sort options and the output updates in real time.

### Does the tool work offline?

Once the page has loaded, all processing happens locally in your browser. You can disconnect from the internet and continue sorting text without any issues.
