JSON Toolbox is one page that replaces three or four separate sites: format and minify JSON, validate it, repair broken JSON, diff two documents to see what changed, and convert between JSON and CSV, XML, or YAML. Everything runs client-side in the browser, so pasted JSON, whether it is an API response, a config file, or anything else sensitive, is never uploaded to a server. No signup, no ads, dark mode included.
would love to see a JSONPath query field next to the tree view so I can filter or extract specific nodes without leaving the page.
client-side JSON tools are always appreciated, and the no upload angle is a real plus for working with sensitive configs. one thing that would make this a daily driver for me is a jsonpath or jq style query bar so you can extract or filter specific keys from a messy payload without scrolling endlessly.
Runs entirely in the browser, which is a huge plus when dealing with sensitive API responses. The diff tool caught a subtle key change between two configs for me in seconds.
the all-in-one approach is genuinely useful, especially having repair and diff right next to the formatter. the client-side only promise sealed it for me since i often paste real api responses i would not want hitting a random server.
The client-side approach is what sold me here, no more pasting sensitive API payloads into random web tools and hoping for the best. The JSON to YAML conversion worked cleanly on a messy config I threw at it.
Love that everything runs client-side, makes it actually safe to paste real API responses without thinking twice. The all-in-one approach beats bookmarking five separate tools.
