🚀 KEY FEATURES:
• Multiple View Modes: Switch seamlessly between Raw, Tree, and Graph visualizations to understand your data architecture.
• Advanced JSON Editor: Edit, format, and minify JSON data on the fly with real-time error validation.
• JSON Diff Checker: Instantly compare two JSON objects to highlight line-by-line additions, deletions, and modifications.
• Format Conversions: Convert your JSON data into YAML or CSV formats with a single click.
• Data Exporting: Easily download your formatted JSON, YAML, or CSV data straight to your local machine.

• Bookmark Integration: Save your favorite formatted endpoints directly to your Chrome bookmarks.

Built with performance in mind, JSONFormatter Pro works completely offline and processes data locally on your machine to ensure your sensitive JSON payloads remain secure and private.
