Add Line Breaks

Split text into clean, readable lines — by character, word, or sentence

A wall of text without line breaks is hard to read, harder to edit, and impossible to format in most layouts. Sometimes you need to break a long string into shorter lines (to fit a fixed-width display, to format an email, to wrap code comments). Sometimes you need to split a paragraph into one sentence per line for editing. Sometimes you need to convert a comma-separated list back into a line-per-item format. This Add Line Breaks tool handles all of those operations.

How it works

Drop your wall-of-text or long paragraph into the editor. Choose where you want the line breaks inserted: after every N characters, after every N words, after every comma, after every sentence, or after a specific custom delimiter. Click Apply. The output appears with line breaks in the right places — and you can copy it straight into a document, a code comment, an email body, or anywhere else.

The break modes explained

After N characters wraps text at a fixed character width. This is the right choice for fitting text into a fixed-width display, a code comment in a language with a strict line-length style guide (PEP 8 in Python uses 79 chars; Black uses 88; many JS style guides use 80 or 100), or formatting plain-text email bodies (traditional email standard was 76 chars per line).

After N words wraps text after a fixed number of words, regardless of how long those words are. Useful for poetry, prose formatting, and creating line breaks that respect word boundaries even if the result is not uniform character width.

After every comma converts comma-separated content into a clean line-per-value list. The classic case is pasting a CSV row and getting a vertical list of values for further processing.

After every sentence identifies sentence-ending punctuation and inserts a break after each one. This is a powerful editing trick: one sentence per line makes it much easier to spot run-on sentences, repetitive sentence starters, and inconsistent rhythm.

Custom delimiter lets you specify any character or string. If your input uses a pipe (|) or a tilde (~) as a separator, just type it in and the tool will break on it.

Real-world uses

Formatting code or technical text. A long string literal that should fit within a line-length limit can be broken at sensible boundaries automatically.

Improving editorial readability. Many editors recommend writing in "one sentence per line" while drafting, then re-joining for publication. It forces you to evaluate each sentence on its own.

Preparing CSV data for vertical inspection. A comma-separated row pasted from a spreadsheet becomes a tall list, each value on its own line, making it easy to scan, sort, or de-duplicate.

Splitting concatenated content from logs. Some logging systems collapse multi-line messages into a single line with a custom separator. Adding line breaks back recovers the readable form.

Twitter and social-media drafting. Breaking a long social media draft at sentence boundaries makes it easier to see whether each line works on its own as a pull-quote — a common technique for high-engagement posts.

Plain-text email composition. Older email clients and mailing-list archives often display long lines awkwardly. Pre-formatting your message to 72–76 character lines avoids ugly mid-word wrapping.

Tips

When breaking by character count, the tool can be configured to break only at word boundaries — so a 60-character break will not split a word in half, but will instead break at the last space that fits inside 60 characters. This is the "word wrap" behaviour most editors use.

If your input has a custom separator that is also a normal character (e.g. a comma in the middle of an address), splitting on it will produce broken lines. Look at the data carefully before choosing a separator.

For very long inputs, the operation is still instant — every modern browser handles megabyte-scale string operations without noticeable lag.
