Hey Product Hunt 👋
I'm the maker of jsonformater.com. It started with one frustration: someone would send me a giant, minified JSON blob — from a database column, a log line, an API response — and I'd have to hunt for a site to make it readable, without pasting sensitive data into some random server.
So I built a fast, privacy-first home for JSON. The part I'm most proud of:
🫧 JSON Blob Viewer — paste or load any blob (even huge, deeply nested ones) and instantly explore it as a clean, collapsible tree.
🔗 Save & Share — save a JSON blob and get a shareable link. Perfect for bug reports, code reviews, and sending data to a teammate without Slack mangling it.
And around that, 30+ tools that all run 100% in your browser — your data never leaves your device:
• 🧹 Format, validate & diff JSON
• 🔄 Convert JSON ↔ CSV, YAML, XML, Excel, TOML, TOON
• 🧑💻 Generate code for 8 languages (C#, TS, Go, Python, Java, Rust, Kotlin, PHP)
• 🔐 Decode JWTs, test JSONPath, generate JSON Schema, explain cron
Free, no sign-up, installable as a PWA.
I'd love your feedback — what do you usually do with a messy JSON blob, and what would make sharing it easier? 🙏
How does the JSON to Excel conversion handle deeply nested arrays, and is there any file size limit for the blob viewer on the free plan?
Love how clean the interface is, no clutter, just paste and instantly see formatted JSON. The one-click Excel conversion is a really thoughtful touch for anyone working with data exports.
Love how clean the layout is, especially the side-by-side JSON-to-Excel conversion. Feels like it was built by someone who actually uses these tools daily, not just tossed together for a launch.
