Chrome JSON Formatter

Transform raw JSON into readable, collapsible tree views

chrome

A Chrome extension that makes JSON data readable and navigable instantly. Whenever you open a json file in the browser, it transforms the raw data into a properly formatted, collapsible tree structure.

What we love ❤️

  • Works instantly without any configuration needed
  • Formats and validates JSON locally in your browser
  • Collapsible tree view for easy navigation
  • Has dark mode 🙌
  • Has buttons for toggling between raw and parsed JSON

Worth noting 💡

  • Chrome only - no Firefox or Edge versions
  • Only works with valid JSON data
  • Some very large JSON files might take time to format

While JSON formatting might seem like a simple task, this extension shows how focusing on core functionality leads to better tools. It does exactly what you need when viewing JSON data - makes it readable and navigable, without adding unnecessary complexity.
