JSON tree viewer — explore nested JSON visually
Paste any JSON object or array and explore its structure in a collapsible tree. Click the arrow next to any object or array to expand or collapse it. Types are color-coded: strings in green, numbers in blue, booleans in yellow. To format raw JSON first, try JSON Formatter. To generate a JSON Schema from your JSON, use JSON Schema Generator.
