YAML & JSON Pretty Viewer

View JSON and YAML files directly in the browser with pretty printing instead of downloading them.

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.
