What are Line Tools?

Line Tools are plain-text operations that treat each row as a unit. They help clean pasted lists, normalize logs, prepare copied spreadsheet values, and reshape developer data without parsing or executing it.

Common developer use cases

Clean log excerpts, sort environment keys, remove repeated IDs, add bullet prefixes, convert comma-separated values into rows, and normalize copied code or documentation snippets.

LF vs CRLF

LF uses a single line-feed character and is common on Unix-like systems. CRLF uses carriage return plus line feed and is common in Windows-oriented files and some network formats.

Deduping safely

Keep case-sensitive duplicate detection enabled when exact values matter. Disable it when copied human-readable lists should treat Status and status as the same line.

Sorting and order

Sort lines before adding prefixes or line numbers when you need stable alphabetical output. Reverse and shuffle run after sorting, so Process can create a new shuffle order.

Line numbers

Remove line numbers handles simple leading patterns such as 1., 1), 1:, and [1]. Add line numbers after cleaning so counts match final rows.

Tips & best practices

Load a sample to see operation order, use custom line endings only for formats that require them, and download TXT when output contains invisible line-ending changes.

Line Tools FAQ

Does Line Tools upload my text?

No. Splitting, trimming, sorting, deduplication, copy, and downloads run locally in your browser.

Does this execute code snippets or logs?

No. Input is handled as plain text only. The tool does not execute JavaScript, shell commands, templates, Markdown, HTML, or any other content.

What operation order does Line Tools use?

The tool splits first, then trims and cleans, removes duplicates, sorts or reorders, adds prefixes, suffixes, or numbers, and finally writes the selected line ending.

Can I preserve the original order while removing duplicates?

Yes. Keep Preserve original order enabled to keep the first occurrence of each line in place. Sorting, reversing, or shuffling can still reorder the final output afterward.

When should I use CRLF instead of LF?

Use CRLF when a Windows-oriented file, legacy tool, or protocol expects it. Use LF for most modern code, configuration, scripts, and Unix-like environments.
