Hey Product Hunt! 👋
I'm Shyam, the maker of PlayWithJSON.
I built PlayWithJSON to make everyday JSON tasks easier for developers. While working with APIs and development projects, I often needed quick tools to format, validate, compare, and convert JSON without switching between multiple websites.
So I brought these utilities together in one simple, browser-based toolkit.
✨ What you can do with PlayWithJSON:
Format and beautify JSON
Validate JSON and JSON5
Minify JSON
Compare JSON data
Convert JSON to YAML
Generate mock JSON data
Work with multiple tabs
It's free to use, and the goal is to keep developer workflows simple and productive.
I'd love your feedback!
