So I built my own.</p> <h3> What it does </h3> <ul> <li>JSON Viewer (Tree + Code)</li> <li>JSON Validator &amp; Minifier</li> <li>JSON → CSV / Excel / YAML</li> <li>CSV → JSON</li> <li>JWT Decoder</li> <li>Base64 Encode / Decode</li> <li>UUID Generator</li> </ul> <h3> Key points </h3> <ul> <li>🚫 No signup</li> <li>🔐 Client-side processing</li> <li>⚡ Very fast</li> <li>🌙 Dark &amp; Light mode</li> </ul> <p>👉 Try it here: <strong><a href="https://jsonviewertool.com/" rel="noopener noreferrer">https://jsonviewertool.com/</a></strong></p> <p>Feedback welcome 🙌</p> showdev json webdev developer
