Split text by delimiter, line break, word, character, regex pattern, or fixed character length, then copy or download the result. All processing happens in your browser, with no uploads or storage.
Flexible splitting
Use delimiters, regex, lines, words, characters, or fixed-size chunks.
Clean output
Trim whitespace, drop empty values, and export as lines, JSON, or CSV.

Split Text by Delimiter, Regex, Lines, Words, or Length
Use this text splitter when you need to turn one text block into organized pieces. It works for simple comma-separated lists, tab-separated spreadsheet values, pasted paragraphs, mixed separators, newline-delimited data, and long text that needs to be chunked into smaller sections. The tool is designed for practical text cleanup, data preparation, content workflows, and everyday productivity tasks.
Split Text by Delimiter
- Separate comma-separated, pipe-separated, semicolon-separated, or tab-separated text
- Use escaped delimiters such as \n for line breaks and \t for tabs
- Trim surrounding spaces so messy pasted lists become clean output
- Convert separated values into one item per line, JSON, or CSV
Split Text by Regex
- Use regular expressions for advanced separators and mixed delimiter cleanup
- Split on multiple separators such as commas, semicolons, pipes, or repeated spaces
- Catch inconsistent formatting in pasted data without editing every line
- See invalid regex errors before copying or downloading results
Split Text into Chunks
- Break long text into fixed-size character chunks for prompts, messages, or exports
- Split paragraphs into lines, words, or individual Unicode characters
- Track total parts, input characters, longest part, and average part length
- Download the processed text as a plain TXT file for later use
How to Split Text Online
- 1Paste or type your textAdd the content you want to split into the input area. The text splitter works with lists, paragraphs, CSV-style values, logs, prompt text, and plain documents.
- 2Choose a split modeSelect delimiter, lines, words, characters, fixed size, or regex. Use delimiter mode for simple separators and regex mode for mixed or complex patterns.
- 3Clean the split partsEnable trimming to remove extra spaces around each part, and remove empty parts to drop blank results caused by repeated delimiters or empty lines.
- 4Pick an output formatOutput each part on its own line, add blank lines between parts, export a JSON array, or create a CSV row depending on where you will paste the result.
- 5Copy or download the resultCopy the processed output to your clipboard or download it as a text file. Everything runs locally in your browser for private text processing.
Text Splitting Modes Explained
Delimiter Splitter
Best for comma-separated lists, pipe-separated values, tab-separated data, tags, categories, product codes, and pasted spreadsheet cells. Delimiter mode is the fastest choice when you know the exact separator.
Input: apple, banana, cherry. Delimiter: comma. Output: apple / banana / cherry.
Line Splitter
Best for turning a block of text into individual lines, cleaning lists copied from documents, separating log rows, or preparing content for sorting and duplicate removal.
Input: one item per row. Output: each row becomes one separate part.
Word Splitter
Best for extracting words from a paragraph, checking repeated terms, building keyword lists, or preparing text for word-level analysis before using a word counter or duplicate finder.
Input: split this sentence. Output: split / this / sentence.
Character Splitter
Best for separating Unicode characters, inspecting spacing, preparing character-by-character transformations, or creating data where each symbol needs its own line.
Input: ABC. Output: A / B / C.
Fixed Size Chunk Splitter
Best for breaking long text into equal-length chunks for prompts, SMS limits, database fields, social captions, code comments, or any workflow with character limits.
Input: 240 characters. Size: 80. Output: 3 chunks of up to 80 characters.
Regex Splitter
Best for mixed separators, irregular whitespace, custom token rules, and advanced cleanup. A regex such as \s*[,;|]\s*|\n+ can split on commas, semicolons, pipes, or line breaks.
Input: apple; banana | cherry. Regex: \s*[,;|]\s*. Output: apple / banana / cherry.

What Can You Use a Text Splitter For?
Data Cleanup
Split messy lists into clean rows before importing them into spreadsheets, databases, CMS fields, CRM tools, email tools, or reporting dashboards.
Developer Workflows
Break logs, stack traces, request payloads, query strings, environment values, or long strings into readable parts before debugging or formatting.
Content and SEO Tasks
Separate keywords, tags, titles, meta descriptions, URL lists, or article ideas into clean items for planning, auditing, or publishing workflows.
Prompt and Message Chunking
Split long text into fixed-size chunks for prompts, chat messages, summaries, content migration, or tools with strict character limits.
CSV and List Conversion
Convert comma-separated values into one item per line, or take cleaned split parts and export them as CSV or JSON for another tool.
Office Productivity
Clean copied tables, notes, meeting action items, bulk names, product lists, addresses, and document text without installing spreadsheet macros.
Text Splitting Tips
Use delimiter mode for exact separators: If your text uses one clear separator such as a comma, pipe, tab, or line break, delimiter mode gives the cleanest result.
Use regex mode for inconsistent data: If pasted text mixes commas, semicolons, pipes, and line breaks, regex mode can split everything in one pass.
Keep trim enabled for most cleanup tasks: Trimming removes unwanted spaces around split parts, which is especially helpful for CSV-style lists and copied spreadsheet data.
Choose JSON for developers and CSV for spreadsheets: JSON output is useful for code and APIs, while CSV output is easy to paste into Excel, Google Sheets, and databases.
Frequently Asked Questions
What is a text splitter?
A text splitter is an online text utility that breaks one block of text into multiple parts using a chosen separator, line break, word boundary, regex pattern, or fixed character length.
Can I split text by comma, tab, or line break?
Yes. Use delimiter mode for commas, tabs, pipes, semicolons, or custom separators. You can enter escape sequences like \n for line breaks and \t for tabs.
Can I split text with regular expressions?
Yes. Regex mode lets you split text using a JavaScript regular expression, which is helpful for mixed separators, repeated whitespace, or inconsistent pasted data.
Is this text splitter private?
Yes. The splitting, cleanup, copying, and download steps happen in your browser. Your text is not uploaded to a server or stored by the tool.
What output formats are supported?
You can output one part per line, add blank lines between parts, create a JSON array, or create a CSV row that can be pasted into spreadsheets and data tools.
Can I split long text into equal chunks?
Yes. Fixed size mode splits long content into chunks by character count, which is useful for prompts, messages, database fields, and platforms with character limits.
