Description
Clean, transparent, privacy-first JSON formatter. 100% local processing. JSONClean is a privacy-first JSON viewer built for developers who care about transparency. When your browser opens a .json file or an API response, JSONClean automatically renders it as a clean, collapsible tree. No more squinting at a single line of minified JSON. Every Pro tool runs locally in your browser. No JSON ever leaves your device. ━━ Why JSONClean ━━ Built from scratch on Manifest V3 with the minimum possible permissions. Zero telemetry. Zero remote code. Operated by a single independent developer — no investors, no acquisition risk. ━━ Free for everyone ━━ ✓ Auto-formats JSON responses and .json files ✓ Collapsible tree view with item counts at every level ✓ Expand all / Collapse all shortcuts ✓ One-click copy (raw or pretty-printed) ✓ Light / Dark / Auto theme ✓ Handles large arrays with paginated rendering ✓ Works offline — 100% local processing ✓ Zero telemetry, zero analytics, zero remote code ━━ Pro tools ($2/month — all 100% local) ━━ 🔍 Search Filter by keys, values, or regex. Jump between matches with Prev / Next. Current match is highlighted in orange so you always know where you are. ⛓ JSONPath Run queries like $.users[*].name or $..price.
