At this desk: JSON studio
Format or minify valid JSON. Expand the tree to inspect values. Errors include a UTF-16 offset and line/column.
Numbers, duplicate property names, key order, and string escapes remain as written. Whitespace outside strings changes. No schema validation.
Limits: 5 MiB UTF-8, depth 128, 100,000 nodes, 32 MiB output. Tree preview shows up to 1,000 nodes.
Clear session removes application references, not downloaded files or browser/OS memory. Ordinary application asset requests still reach the host. There is no analytics, content persistence, or processing service.
