Building this tool has been a passion project to make JSON visualization simple, fast, and enjoyable. I created it for developers who want clarity, not complexity.

I tried JSON Viewer and actually found it really useful. It turns messy JSON blobs into clean, interactive diagrams and tree-views — so you can instantly see the structure, dive into nested objects, or collapse parts you don’t care about. The search & filter, side-by-side comparison, and export options (CSV / PNG / YAML etc.) make debugging or analyzing JSON far easier than digging through raw code. For developers, analysts, or anyone working with APIs, configs or nested data, this tool saves time and mental friction. Clean UI, easy to use — well done.
