Why use a text splitter?
Turn one blob into CSV-ready fields, SMS-sized chunks, or per-line records without installing software.
Benefits
- Delimiter mode: break lists on commas, pipes, tabs, or custom tokens.
- Chunk mode: cap length by characters, words, or line batches.
- Lines mode: treat every newline as a split.
- Visual gaps: --- dividers make parts easy to scan.
- Private: runs entirely in the browser.
How it works
The tool applies string split or slicing rules you choose, then joins the resulting segments with a fixed separator so you get one textarea of output.
Features
- Literal delimiter: JavaScript string split—no regex in this tool.
- Chunk sizes: slider ranges depend on chunk type (chars, words, lines).
- Words: tokens from splitting on whitespace.
- Copy: take the block or manually split on the dividers.
- Live updates: output tracks input and settings.
When to use
Quick CSV field previews, message batching, log line extraction, or teaching string basics.
Ideal use cases
- Lists: comma- or pipe-separated lists into parts.
- Length limits: character or word caps per chunk.
- Line extraction: every row as its own segment.
- Drafts: prototype splits before scripting.
- Privacy: data never uploaded.
Facts
Behavior notes.
Key points
- Empty delimiter splits between each character (JavaScript default).
- Lines mode keeps empty lines as empty segments between dividers.
- Chunk word mode collapses whitespace between words in each chunk.
- Very large inputs may hit device memory limits.
- Rich formatting from Word/HTML is not preserved—use plain text.
Best practices
Reliable results.
Quality considerations
- Match delimiter to your file’s real separator (watch spaces after commas).
- Preview before feeding output into production pipelines.
- For strict CSV, use a CSV-aware tool if quoting matters.
- Try a small sample on huge pastes.
- Code and structured data: review splits manually.
When not to use
- When you need regex-based or locale-aware rules.
- When CSV escape sequences and quoted commas matter.
- When only a database should define record boundaries.
Limitations and compatibility
Plain text; delimiter is literal substring split. Requires JavaScript. Separator between parts is fixed (---) in the output area.
Text splitting runs fully in your browser with no server upload; results update instantly as you switch modes and adjust settings.
Frequently asked questions
Is the text splitter free?
Yes. Splitting runs in your browser. No registration or upload.
Can I use a custom delimiter?
Yes. Type any literal string: comma, semicolon, tab character, or a multi-character delimiter.
What is chunk splitting?
The text is cut into segments of equal length: by character count, by word count (whitespace-separated words), or by grouping N lines together.
Is my text secure?
Yes. Processing stays on your device.
How are parts separated in the output?
Each part is separated by a line with three dashes (---) on its own, so you can see boundaries in one pasted block.
