Overview

Introduction

Breaking delimited text into individual pieces, comma-separated values, pipe-delimited fields, is one of the most common text operations.

This tool does it with any delimiter you choose.

What Is Text Splitter?

A splitter that breaks text at every occurrence of your chosen delimiter and lists the pieces one per line.

It runs entirely client-side as part of this site's String Tools collection, so nothing you paste is ever uploaded to a server.

How Text Splitter Works

The tool calls input.split(delimiter) and joins the resulting array with newlines for display.

The transformation happens synchronously in JavaScript the moment you type, with no network round trip involved.

When To Use Text Splitter

Use it to break a delimited list into individual items for review, sorting, or further processing.

It's a fast way to get the answer without opening a code editor, a REPL, or writing a one-off script just to check.

Often used alongside Text Joiner and Regex Match Extractor.

Features

Advantages

  • Works with any literal delimiter, not just commas.
  • Output is immediately usable as a line-per-item list.

Limitations

  • Delimiter matching is literal, not regex-based.

Examples

Splitting a CSV row

Input

one,two,three,four

Output

one
two
three
four

Each comma-separated value becomes its own line.

Best Practices & Notes

Best Practices

  • Use Join Strings afterward if you need to recombine the pieces with a different delimiter.

Developer Notes

This is a direct call to the native String.prototype.split(delimiter), with the resulting array joined by newlines purely for display in the output panel.

Text Splitter Use Cases

  • Breaking a CSV row into individual values
  • Splitting a pipe-delimited log line into fields
  • Converting a delimited list into a one-per-line list for sorting

Common Mistakes

  • Expecting regex support in the delimiter field; matching is literal.

Tips

  • Use Join Strings to recombine the split pieces with a new delimiter.
