FORMAT & MINIFY
Beautify messy JSON into clean, readable code with one tap — or minify it down to a single compact line. Perfect for API responses, configs, and OpenAPI/Swagger files.
INSTANT VALIDATION
Know immediately if your JSON is valid. Errors are detected on the fly, with the exact line and column highlighted so you can fix them in seconds.
TREE VIEW
Explore complex JSON as an interactive, color-coded tree. Expand or collapse everything at once, search keys and values, and copy any value with a click.
MODEL EXPORT (SWAGGER-STYLE)
Generate ready-to-use data models straight from your JSON — Swift (Codable), Kotlin, and TypeScript — just like editor.swagger.io. Copy or save the generated code and drop it right into your project.
MULTI-DOCUMENT WORKSPACE
Keep all your JSON files in one place. Open many documents at once, switch between them instantly from the sidebar, rename, duplicate, and organize them into groups.
BUILT FOR BIG FILES
A fast native engine handles large JSON and API specs smoothly — thousands of lines, no lag.
SYNTAX HIGHLIGHTING & LINE NUMBERS
Read your JSON comfortably with full syntax coloring, line numbers, and clear error markers.
DRAG & DROP
Just drop one or more JSON files onto the window to start working immediately.
