About JSON Formatter
Format, beautify, minify, and validate JSON directly inside your browser.
What it does
Paste raw text to format, compress, or validate payloads against RFC 8259 specifications. Inspect structured data through an interactive tree view, or sort keys following ECMAScript object traversal order. Everything executes on your device.
Why it exists
A formatter that processes JSON on a remote server requires you to send your payload to that server. Pasting private API responses, authorization tokens, or internal logs into a tool built that way puts that data outside your control. JSON Formatter never sends your input anywhere.
Who it is for
Written for developers, QA engineers, and API integrators who inspect payloads daily. Parse server responses, verify webhook payloads, and diagnose malformed syntax without waiting on a security review.
How your data is handled
Your input stays on your machine. The site is served as static files from Cloudflare Pages. The code ships with no analytics scripts, no advertising trackers, and no outbound network requests.
