About the JSON Formatter & Viewer
JSON (JavaScript Object Notation) is the most common format for exchanging data between web services. Minified JSON from an API is hard to read, and a single missing comma or bracket can break parsing. This tool fixes both problems: it validates the structure and shows it as an interactive, syntax-highlighted tree so deeply nested data is easy to explore.
The dual-pane editor gives you a code view on the left and a collapsible tree on the right. You can expand or collapse any branch, search for keys or values, and Shift-click any key to reveal its JSONPath — handy for writing queries against the data.
Everything runs in your browser using the native JSON engine, so it is fast and your data never leaves your device. Beautify uses two-space indentation; Minify strips all optional whitespace for the smallest possible payload.
Frequently asked questions
Does this validate my JSON?
Yes. If the JSON is malformed, the tool shows a clear error instead of formatting it.
Is my JSON uploaded anywhere?
No. Parsing and formatting happen entirely in your browser.
What indentation does Beautify use?
Two spaces, which is the most common convention for readable JSON.
