Text Splitter

What is a text splitter?

A text splitter takes one long block of text and breaks it into smaller, separate pieces. You decide where the breaks happen. In delimiter mode the tool cuts the text wherever it finds the separator you choose — a single character, a space between words, a line break, a custom string such as a pipe or a slash, or a regular expression for advanced patterns. In chunk mode the tool ignores delimiters and instead breaks the text into fixed-size blocks: every N characters, or every N words. The result is a list of pieces that you can clean up, count, and copy in one click.

How to split text into pieces

Splitting text takes just a few seconds:

1. Paste or type your text into the text box.
2. Pick a mode: Split by delimiter, or Chunk by size.
3. For delimiter mode, choose Character, Word, New line, a Custom string, or Regex, and type the delimiter or pattern if needed.
4. For chunk mode, choose Characters or Words and set the chunk size.
5. Pick how to join the pieces — one per line, comma, space, or a custom separator — turn on Trim or Drop blanks if you like, then click Split text and copy the result.

Splitting by character, word, line, custom string, or regex

Delimiter mode covers the most common ways to break text apart. Character splits the text into individual characters, so each letter, digit, or symbol becomes its own piece. Word splits on whitespace, turning each word into a piece. New line breaks the text wherever a line ends, which is handy for processing pasted rows. Custom string lets you type any separator — a comma, a pipe, a tab, a slash, or even a whole word — and the text is cut at every occurrence. Regex unlocks pattern-based splitting: supply a regular expression and the text is split wherever the pattern matches, ideal for separators that vary.

Breaking text into fixed-size chunks

Chunk mode is for splitting by character count or word count instead of by a separator. Choose Characters and a size of, say, 280 to break a long message into pieces that each fit a character limit, or choose Words and a size of 50 to break an article into blocks of fifty words. The tool walks through the text and emits a new piece every time it reaches the size you set, so the last piece holds whatever is left over. This is the quickest way to split text by character count or chunk text into equal parts.

Trim, drop blanks, and choosing the output separator

Two cleanup options tidy the result. Trim each piece removes leading and trailing spaces from every piece, so stray spacing around a delimiter does not end up inside your output. Drop blank pieces removes empty pieces, which is useful when the text has repeated separators or trailing breaks. Finally, the join option controls how the pieces are written out: one piece per line for a clean list, comma-separated for a single line of values, space-separated, or a custom separator you type yourself. The piece count updates so you always know how many pieces you produced.

Why use this text splitter?

• Split text by character, word, new line, a custom string, or a regular expression.
• Chunk text into fixed-size pieces by character count or word count.
• Trim each piece and drop blank pieces for a clean result.
• Choose how pieces are joined — one per line, comma, space, or a custom separator.
• See a live count of how many pieces you produced and copy them with one click.
• Runs entirely in your browser — your text is never uploaded or stored.
