I built one place for all of it.<br> 🔗 <a href="https://jsonviewer.live" rel="noopener noreferrer">https://jsonviewer.live</a></p> <p><strong>jsonviewer.live</strong> — 8 tools in one:</p> <p>• { } JSON Formatter &amp; Tree Explorer — format, validate, search keys/values<br> • 🔑 JWT Decoder — decode header/payload, verify HMAC-SHA256 signatures<br> • ⇄ Base64 Encoder/Decoder — standard + URL-safe, file upload support<br> • .* Regex Tester — live match highlighting, match table with groups<br> • 🕐 Unix Timestamp Converter — all formats, any timezone, relative time<br> • 🎨 Color Picker — HEX/RGB/HSL/HSB, shade generator, WCAG contrast checker<br> • # UUID Generator — v4/v1/v7, bulk generation, download as .txt or .json<br> • ▦ QR Code Generator — URL, Wi-Fi, vCard, email, SMS — download PNG/SVG</p> <p>🔗 <a href="https://jsonviewer.live" rel="noopener noreferrer">https://jsonviewer.live</a></p> <p><strong>What makes it different:</strong></p> <ul> <li>Zero backend. Everything runs in your browser — paste sensitive tokens, internal configs, private data without worrying where it goes</li> <li>Works offline after first load</li> <li>Dark + light mode</li> <li>Mobile friendly</li> </ul> <p>It's fully open source. Would love feedback on what tools to add next.</p> <p>🔗 <a href="https://jsonviewer.live" rel="noopener noreferrer">https://jsonviewer.live</a><br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4ap79a1crdfevbqeg4zn.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4ap79a1crdfevbqeg4zn.png" alt=" " width="800" height="412"></a></p> Harshit Bagauli Sun, 14 Jun 2026 11:47:31 +0000 https://dev.to/harshit_bagauli_9f7580db4/i-built-a-free-json-viewer-that-never-uploads-your-data-heres-how-km https://dev.to/harshit_bagauli_9f7580db4/i-built-a-free-json-viewer-that-never-uploads-your-data-heres-how-km <p>As a developer, I constantly paste JSON into online tools — but always felt uncomfortable about where that data was going. So I built JSON Viewer Pro.</p> <p>What it does<br> Paste JSON → instant collapsible tree view<br> Click any node → get the JSONPath ($.user.address.city)<br> Search across all keys and values<br> Format or minify with one click<br> Dark &amp; light theme<br> The privacy angle<br> The entire app is a single HTML file served from Cloudflare. There is no backend, no database, no analytics. Your JSON is processed entirely in your browser using JSON.parse().</p> <p>Try it<br> <a href="https://jsonviewer.live" rel="noopener noreferrer">https://jsonviewer.live</a></p> <p>Built with vanilla JS, no frameworks.
