Hi everyone,

I built a small web tool called Datamorph because I kept running into JSON/CSV converters that either broke with nested data, required login, or added weird formatting.

Datamorph is a minimal, fast, no-login tool that can:

• Convert JSON → CSV and CSV → JSON • Auto-detect structure (arrays, nested objects, mixed data) • Handle uploads or manual text input • Beautify / fix invalid JSON • Give clean, flat CSV output for real-world messy data

It’s built with React + Supabase + serverless functions. Everything runs client-side except file parsing, so nothing is stored.

I know there are many similar tools, but I tried focusing on:

• better handling of nested JSON, • simpler UI, • zero ads / zero login, • instant conversion without waiting.

Would love feedback on edge cases it fails on, or features you think would make this actually useful for devs and analysts.

Thanks for checking it out!
