Format And Validate JSON Online
A JSON formatter is useful for developers, testers and website owners who work with API responses, configuration files, structured data and app settings. Raw JSON can be difficult to read when it is minified or deeply nested.
This tool formats JSON with clean indentation and also checks whether the input is valid. You can switch between beautified JSON and minified JSON depending on whether you need readability or compact output.
Because the formatter runs in the browser, it is quick for everyday JSON snippets and does not require uploading data to a server.
