Linebreaker

Linebreaker enhances the readability of HTTP messages by automatically rendering escaped newline sequences (\n) as actual line breaks in a dedicated message editor tab. This simple yet effective tool improves the analysis and modification of request and response data containing formatted content.

Features

  • Dedicated "Newline View" tab in all message editors throughout the suite
  • Real-time conversion of escaped newlines (\n) to proper line breaks
  • Full editing capabilities with preservation of modified content
  • Maintains message integrity when content is not modified
  • Works seamlessly with both HTTP requests and responses
  • Automatic detection and formatting of newline-escaped content

Usage

  1. Navigate to any HTTP message within the suite (Proxy, Repeater, Intruder, etc.)
  2. Look for the "Newline View" tab in the message editor
  3. Click the tab to view content with escaped newlines properly formatted
  4. Edit the content directly if needed — changes will be preserved
  5. Use the formatted view to better understand JSON, XML, or other structured data
