What it does

JSON Tools is a free suite of 9+ in-browser utilities: JSON viewer (collapsible tree), formatter, validator, minifier, diff, and converters (JSON ↔ CSV/XML/YAML/TypeScript). Everything runs 100% in your browser—no uploads, no accounts, no data sent to servers. Paste JSON, search keys/values, copy JSONPath, and convert formats fast. Built for developers who want fast, private, clutter-free JSON tools.
