What can Line Utilities do?
Line Utilities is a Swiss-army knife for text lists. Sort alphabetically, reverse the order, shuffle randomly, remove duplicate lines, trim leading and trailing spaces from each line, remove blank lines, or prepend line numbers — all with a single click.
Common use cases
Cleaning up CSV columns, deduplicating email lists, randomising quiz questions, sorting word lists for study, numbering code snippets, and preparing data for import into spreadsheets or databases.
Why use Line Utilities online?
Line Utilities in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.

Frequently Asked Questions
- Can I apply multiple operations in sequence?
- Yes — each button transforms the current output. Apply Sort A→Z, then Remove duplicates, then Number lines, for example, and each step builds on the previous result.
- Is duplicate removal case-sensitive?
- You can toggle case sensitivity. With it on, 'Apple' and 'apple' are treated as different lines. With it off, only one is kept.
- How does shuffle work?
- Lines are shuffled using the Fisher-Yates algorithm, which gives a uniformly random permutation each time you click.
- Is there a line limit?
- There is no hard limit. The tool runs entirely in your browser and handles thousands of lines comfortably.
- Is this tool free to use?
- Yes. All Skybin developer tools are free with no account, API key, or usage limits.
- Does my data get sent to a server?
- No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).
- Can I use this on mobile?
- Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.
- How is this different from desktop apps?
- There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.
- Are there keyboard shortcuts?
- Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.
- Does Skybin store my history?
- No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.
