    Datamorph – A clean JSON ⇄ CSV converter with auto-detect▲26

    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.

    GetJSON, make ajax requests to anywhere▲7
