About YAML & JSON Pretty Viewer
Stop annoying file downloads and view JSON and YAML files directly in your browser with beautiful syntax highlighting.
Tired of clicking a link to an API response, configuration file, or raw data feed only to have your browser instantly download the .json or .yaml file to your computer?
YAML & JSON Pretty Viewer intercepts these files and renders them directly in your current tab. Instead of a messy wall of raw text, your code is automatically parsed, indented, and displayed in a clean, developer-friendly dark mode theme.
Key Features:
- Prevents Unwanted Downloads: Forces .json, .yml, and .yaml links to open in the browser instead of cluttering your Downloads folder.
- Syntax Highlighting: Easily distinguish keys, strings, numbers, booleans, nulls, and comments with a color palette inspired by modern code editors.
- Auto-Formatting: Automatically pretty-prints and correctly indents JSON data for maximum readability.
- Dark Mode by Default: Easy on the eyes with a sleek, high-contrast dark theme.
- Lightweight & Fast: Runs instantly without slowing down your browsing experience. Zero configuration required—just install and go.
How it works:
The extension uses minimal permissions to remove the Content-Disposition download header from JSON and YAML web requests, allowing Chrome to safely render the text on screen. It then applies a lightweight, local script to format the raw data.
Privacy Focused:
No user data is collected, tracked, or sent to external servers. All file formatting happens locally on your device in real-time.
