Everyday JSON operations, all in your browser — nothing is uploaded:
- Tree viewer: a collapsible tree is built as you type; if a string is an image link (like
https://...png), hover shows a preview; search-to-locate, expand-all / collapse-all, and a fullscreen new-window view are supported. - Format / Minify: pretty-print with 2-space indent, or squeeze into a single line.
- Sort by key: recursively reorder objects alphabetically by key name.
- Auto-repair: lenient parsing of trailing commas, single quotes, unquoted keys,
//and/* */comments and other non-standard syntax — one click writes back standard JSON. - Copy / Download: standard JSON copied to the clipboard or downloaded as
data.jsonwith one click.
Enter JSON above and the tree is built automatically
