CodePrettify: JS, JSON, CSS & RSS Formatter

A fast, IDE-like viewer for raw JSON, code, and data files: format, validate, fold, search, diff, and inspect.

Automatically format JSON, JavaScript, CSS and XML, and read Markdown as a clean document — directly in your browser. Open an API response, a minified script, a stylesheet or a Markdown file. CodePrettify makes supported raw files easier to read with clear formatting, syntax highlighting and tools for finding what you need. READ AND EXPLORE - Explore JSON with collapsible objects and arrays. - Read rendered Markdown or switch to its original source. - Search with live match counts, jump to a line and copy original or formatted code. - Switch between raw and formatted views. - Choose light, dark or system theme. Adjust font size, indentation and word wrap. WEB AND LOCAL FILES Open supported raw-file URLs, or choose or drop a file in the extension launcher. Files opened through the launcher do not require file-URL access. To view file:// URLs directly, enable "Allow access to file URLs" in your browser's extension settings. ADDITIONAL TOOLS - Run snippets in JavaScript Playground and test patterns in Regex Playground. - Send API requests and inspect responses with HTTP Client. - Compare documents, explore data in tables, validate and convert content, or generate code and diagrams. LOCAL PROCESSING Formatting and analysis run on your device. CodePrettify does not upload your documents to our servers or send us extension usage analytics. No CodePrettify account is required. The viewer handles document content and resource URLs locally. HTTP Client requests go directly to the service you choose. Selected settings can sync through your browser account.
