Split Lines
Break a single line or a block of text into separate lines using any delimiter. Choose commas, tabs, spaces, or type your own custom character — the output updates instantly. Trim whitespace if needed, then copy or download the result. No signup, no uploads — everything runs right here in your browser.
Why use this split lines tool?
Often you have a long string of values — like CSV data, command outputs, or a list separated by commas or pipes — and you need each item on its own line. This tool does exactly that, instantly. No need to open a spreadsheet or write a script. And because it runs entirely in your browser, your data stays private.
- Multiple delimiters – comma, semicolon, pipe, space, tab, or any custom character you want.
- Whitespace cleanup – the trim option removes spaces before and after each piece, keeping the output clean.
- Instant preview – the split text appears as you type (with a tiny delay) or when you click Split.
- No data uploads – all processing is done locally; your text never touches a server.
How to split lines (step‑by‑step)
1. Paste your text
Copy the string you want to split and drop it into the left box.
2. Choose delimiter
Pick the character that separates your items. If it's not in the list, select Custom and type it.
3. Trim (optional)
Toggle "Trim whitespace" if you want spaces before/after each item removed. Usually you want this on.
4. Copy or download
The split lines appear instantly on the right. Use the buttons to copy or save as a .txt file.
Example: splitting CSV data
| Input text (comma‑separated) | Output (split with trim) |
|---|---|
| apple , banana , cherry , date | apple banana cherry date |
Common use cases
- CSV processing: Split a single CSV line into individual rows for easier reading or further tools.
- Command outputs: Break pipe‑delimited data from terminal commands into a readable list.
- Data cleaning: Transform a long string of IDs or keywords into a neat list before deduplication.
- Inventory lists: Turn a comma‑separated shopping list into a checklist, one item per line.
Pro tips
- If your delimiter appears inside the data (e.g., a comma inside a quoted field), this tool performs a simple split — it does not handle CSV quoting. For that, first use our CSV to Text tool.
- Use the space delimiter to split a sentence into words, each on its own line.
- The opposite of this tool is Join Lines, which merges multiple lines back into a single string.
