Working with raw JSON can be tough — especially when you’re dealing with deeply nested data from APIs, databases, or config files. Scrolling through brackets and keys isn’t exactly the most developer-friendly experience.
That’s why I built JSON Viewer Tools — a free tool to make working with JSON visual, interactive, and way less painful.
Key Features
Tree & Graph View – easily navigate nested structures
Table View for CSV – upload CSV and explore it as clean, editable tables
YAML Support – convert and visualize YAML side by side with JSON
Link Hover Visualization – instantly see relationships inside your JSON
Compare JSON Data – quickly find differences between two files
Export as Image – share visualizations with your team
Theme Customization – light, dark, and more
3D JSON Visualization – explore data like never before
Why I Built It
As a developer, I found myself constantly digging into messy JSON responses — debugging APIs, testing databases, or comparing payloads. I wanted something lightweight, visual, and fun instead of staring at endless nested objects. That’s how JSON Viewer Tools was born.
Try it out
jsonviewer.tools
Free. No login required.
I’d love your feedback: which feature would help you the most when working with JSON?
