Hey everyone! I built JSON Purrser because I was tired of jumping between different tools to view, validate, and convert JSON. This is my first ever submission so any feedback/suggestions/ideas are more than welcome! This tool I built has all the killer feature that I was missing when working with similar ones: - Smart field detection: Recognize and preview URLs, dates, colors, coordinates, and even JWTs in your JSON - Easy, quick and automatic validation and fixing of trivial errors: No more search for that missing comma - Workspace for multiple files: FINALLY, all the jsons you have open, in a single place - All the controls you can imagine: Font size control, type toggles, index toggles, you name it - Multiple themes: Because everyone is different and just light/dark is so old and boring I would love to get any kind your feedback! What features would make this more useful for your workflow? Thanks, Sotiris
