Text splitter
What the text splitter does
This tool splits a block of text into a list using a delimiter you choose, by default a line break, and then cleans up the result: each item is trimmed of leading and trailing whitespace, and any entry that ends up empty is dropped entirely. What comes out is one item per line, with nothing blank and nothing padded.
It runs in your browser. Paste, choose your delimiter if you need something other than a line break, press Split, copy the result. Nothing is uploaded, and there is no limit on how much text you split or how often you come back.
The problem
A messy pasted list, in plain terms
A list pasted from an email, a spreadsheet column, or a chat reply rarely arrives clean. It carries blank lines where an editor or a chat interface added spacing, trailing spaces on individual entries that a spreadsheet import will choke on, and sometimes a mix of line breaks and commas depending on how it was originally typed.
Turning that into something usable, one clean value per line, with nothing blank and no stray padding, is a small job that is genuinely tedious to do by hand once the list runs past a dozen items.
How it works
How to split text into a list in three steps
The default delimiter is a line break, which covers the most common case without any setup.
- Step 1
- Paste the text you want split into the input box.
- Step 2
- Leave the delimiter as a line break, or change it to a comma, a semicolon or any character your list actually uses.
- Step 3
- Press Split and copy the cleaned list from the output box.
The delimiter
Splitting on something other than a line break
Line breaks are the default because most pasted lists already have one item per line. If your text is comma-separated, semicolon-separated, or separated by any other character, type that character into the delimiter field and the tool splits on it exactly, treating it as literal text rather than a pattern.
Each resulting piece is trimmed and empty results are dropped either way, so a trailing comma or a run of several delimiters in a row doesn't leave blank entries in your output.
The delimiter is matched as literal text, not as a regular expression, which makes it safe to run on source code or structured data such as a CSV row pasted as plain text. A period, a parenthesis or an asterisk typed into the delimiter field is treated as exactly that character, not as a wildcard or a pattern that could match more than you intended.
Why it matters
What a messy list actually breaks
A blank line in a list pasted into a bulk-import tool becomes an empty row that the import either rejects outright or silently stores as a blank record. A trailing space on an entry makes it fail to match an identical-looking value elsewhere, since the two strings are not actually equal.
A list mixing line breaks and commas confuses a script expecting one consistent separator, producing entries that are subtly wrong, half a comma-joined pair sitting on its own line, rather than obviously broken.
Straight answer
Does this split text into sentences or paragraphs?
No. This tool splits on a literal delimiter you choose, a line break or a specific character, not on sentence-ending punctuation or paragraph structure. It has no idea what a sentence is; it only knows where your chosen delimiter sits in the text.
For turning a paragraph into individual sentences, you would need a different kind of tool that understands punctuation and abbreviations. This one is for lists: values that are already separated by something, cleaned up and made consistent.
In practice
Who uses the text splitter, and when
Anyone preparing a bulk import, tags, email addresses, SKUs, uses it to turn a pasted comma-separated blob into one clean value per line before feeding it into a form or a script.
Developers use it to normalise a list copied from documentation or a chat reply before pasting it into an array literal or a config file, and data-entry work uses it to strip blank lines and trailing spaces out of a list before it goes into a spreadsheet.
