Add Line Breaks

Convert long text into multiple lines. Break after punctuation, delimiter, every N characters, or every N words. Includes batch file processing.

What is Add Line Breaks?

Add Line Breaks is a text formatting tool that splits long or single-line text into multiple lines. It's the opposite of "Remove Line Breaks" - instead of joining lines, it creates new line breaks at specific points in your text.

The tool offers multiple ways to split your text: break after punctuation marks (sentences), break at delimiters (like commas), break every N characters, or break every N words. This flexibility makes it useful for a wide range of formatting tasks.

Privacy First: All file processing happens entirely in your browser. Your files never leave your device - no uploads, no server processing, no tracking.

Four Break Modes

Punctuation Mode

Splits text after sentence-ending punctuation. Customize which characters trigger breaks (default: period, question mark, exclamation mark).

Best for: Breaking paragraphs into individual sentences, creating sentence-per-line format for analysis or translation work.

Delimiter Mode

Splits at any delimiter you specify. Perfect for comma-separated lists, pipe-delimited data, or any custom separator.

Best for: Converting CSV data, splitting lists, transforming delimited data into line-by-line format.

Character Count Mode

Creates lines of consistent length. Intelligently breaks at word boundaries when possible to avoid splitting words.

Best for: Character-limited displays, SMS messages, social media posts with strict character limits.

Word Count Mode

Creates lines with a fixed number of words. Ideal for poetry, lyrics, or consistent paragraph formatting.

Best for: Poetry formatting, song lyrics, creating consistent line lengths for visual appeal.

Frequently Asked Questions

How do I split text into sentences?

Use Punctuation mode (the default). Enter the punctuation marks that end sentences - typically ". ? !" - and each sentence will become its own line.

How do I convert a comma-separated list to multiple lines?

Select Delimiter mode and enter a comma (,) in the delimiter field. Each item in your list will appear on its own line.

How does character-count mode handle words?

When breaking by character count, the tool tries to break at word boundaries. If a word would be split, it looks back for the previous space and breaks there instead. This keeps words intact while staying close to your target line length.

What file types can I upload?

The tool accepts common text-based files: .txt, .csv, .md, .log, .json, .xml, .html, .css, and .js.

Are my files uploaded to a server?

No. All processing happens entirely in your browser using JavaScript. Your files never leave your device, ensuring complete privacy and security.

Can I use multiple punctuation marks?

Yes. In Punctuation mode, enter all the characters you want to break after, separated by spaces. For example, . ? ! : would break after periods, question marks, exclamation marks, and colons.

Why are there empty lines in my output?

Empty lines can appear when there are consecutive delimiters or punctuation marks. Enable the "Remove Empty" option to filter these out automatically.
