Can the delimiter be more than one character?

Yes, any literal delimiter string works, not just a single character, since the tool splits on an exact substring match.

Does it support regex delimiters?

No, the delimiter is matched literally. For regex-based splitting, use Extract Regex Matches instead.

What happens with an empty delimiter?

Splitting on an empty string separates every character, giving one character per line. That is occasionally handy, but it is rarely what you want from a delimiter field.

Text Splitter Online - Split Text by Delimiter

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.
Preserves empty pieces, so two adjacent delimiters produce a blank line and the position of a missing value stays visible.

Limitations

Delimiter matching is literal, not regex-based.
Understands no quoting, so a delimiter appearing inside a quoted value splits it exactly like any other occurrence.

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.
Include any surrounding space in the delimiter, using ', ' rather than ',', to avoid a leading space on every piece.
Compare the resulting line count against the number of values you expected, since a stray delimiter quietly adds an empty piece.

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.
Splitting genuine CSV on a comma, which breaks apart any quoted field that happens to contain one.

Tips

Use Join Strings to recombine the split pieces with a new delimiter.
Because the pieces are displayed joined by newlines, a piece that itself contains a newline spans several lines and can look like two separate results.
