Text Splitter — Split by Character or Length

Frequently Asked Questions

How do I use the character splitter?

Paste your text, choose Split by character, and leave the separator empty to split into individual characters. Click Split Text, then copy or download the output.

For example, ABC produces three output lines: A, B, and C. Spaces also become separate output items; they are not automatically removed.

To split a list instead, enter a comma as the separator: red,green,blue produces three lines containing red, green, and blue. A separator can contain more than one character.

How do I split text into fixed-length chunks?

Choose Split by fixed length and enter how many characters each chunk should contain. For example, ABCDEFGH with a length of 3 produces ABC, DEF, and GH on separate lines.

The last chunk may be shorter. This mode can split a word in the middle, so review the result if you need complete words or sentences.

What kinds of splitting jobs is this tool meant for?

Use it when one large text block needs to be broken into smaller chunks for APIs, exports, batch processing, validation, or manual review.

Paste the text, choose the splitting rule that matches your situation, fill in the related option, and click Split Text.

Because the output returns one chunk per line, it is easy to inspect or pass into another text-based workflow.

How do the four split modes differ?

Split by character uses the exact separator you type. It works well for commas, pipes, slashes, or any other delimiter.

Split by regular expression uses a pattern, which helps when the boundary is not always the same character.

Split by fixed length and Split into equal parts divide the text by character count. Use them when a long string needs to stay under a size limit.

What should I know about separators, chunk size, and equal parts?

If the character separator field is empty, the tool falls back to splitting into individual characters.

Fixed length creates consecutive chunks of the size you enter, and the final chunk may be shorter if the text length does not divide evenly.

Split into equal parts spreads the characters as evenly as possible across the number of parts you enter.

Which edge cases should I watch for?

Invalid numbers for fixed length or parts count leave the text unchanged, so check the output if nothing seems to happen.

An invalid regular expression is left unsplit. Check the output if the text does not change.

Consecutive separators can produce empty chunks, so values like 'a,,b' may intentionally create a blank line in the output.

How is this different from Merge Text Lines?

Text Splitter breaks one input into many pieces.

Merge Text Lines does the opposite: it joins many lines with a separator you choose.
