The JSON Workbench.
Format, validate and explore JSON. Inspect any value's path, search the tree, and get clear error messages - fast, private, and entirely in your browser.
Large input - parsing may take a moment.
Your JSON stays in your browser - it is never uploaded, logged, or sent to analytics.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight text format for representing structured data - objects with named keys, arrays of values, strings, numbers, booleans, and null. It's the standard way APIs and config files exchange data.
Formatting vs Minifying
Formatted JSON adds indentation and line breaks so humans can read it easily during development and debugging. Minified JSON strips all unnecessary whitespace to reduce file size - what you'd actually send over a network or store at scale.
Is My JSON Uploaded?
No. JSONLoad parses, formats, and renders your JSON entirely inside your own browser using standard JavaScript. Nothing you paste is sent to a server, logged, or captured by analytics.
