Why Replace Line Breaks in Text?

Replace Line Breaks in Text Quickly replace all line breaks in text with a new character.


Line breaks can be useful in poems or code, but they often become a problem when you're formatting text for blog posts, social media captions, or spreadsheet cells. Pasting multi-line text into a single paragraph field can result in broken sentences or messy formatting. Our Replace Line Breaks tool removes that friction — it merges lines into one continuous string, using a character of your choice.

Common Use Cases

  • Bloggers & Writers: Convert a block of notes into a clean, single-line summary. Insert commas or semicolons to create SEO-friendly meta descriptions or lists.
  • Data Cleaners: Prepare CSV-ready text by replacing line breaks with commas, making it easy to import records into spreadsheets.
  • Social Media Managers: Merge influencer tags or hashtags written on separate lines into a space-separated string ready for Instagram or Twitter.
  • Programmers: Quickly turn a list of phrases into a single-line string for config files, JSON values, or code comments.

How It Works — Securely & Privately

This tool runs entirely in your browser using JavaScript. No text ever leaves your device. It instantly detects all types of line breaks (Windows CRLF, Unix LF, and legacy CR) and replaces them with the character you pick — a space, comma, semicolon, or any custom string like " | ".

Tips for Better Results

  • Custom separator with spaces: Type " , " (comma surrounded by spaces) in the custom field for a more readable list.
  • Remove blank lines first: The tool also collapses multiple consecutive line breaks into a single separator, so no pesky empty spaces remain.
  • Copy with one click: Use the "Copy Result" button to send the cleaned text straight to your clipboard — no manual selection needed.
