A free, browser-based JSON editor, formatter, and validator for developers who want to process JSON without sending data to a server.
[ about ]
JSON Formatter App is an online editor and processing toolkit for JSON data. It lets users format, validate, beautify, minify, and convert JSON, with tools including a JSON Schema validator, a jq runner, JSONPath, and a diff tool. It also converts JSON to and from YAML, XML, TOML, CSV, TypeScript, and several programming languages.
The main selling point is privacy. Processing runs entirely in the browser, with no tracking, no saving, and no servers.
The site is part of a family of developer tools from the same team, with a sister site, IPLookup.tech, mentioned in the footer.
