With this tool you can create a JSON schema and a complete JSON editor with your new input JSON. The JSON Editor is generated in your browser as ZIP file.
The ZIP file is based on jsoneditor_app.zip (see GitHub-Repository: https://github.com/niebert/jsoneditor_app)
and is populated with the generated JSON Schema with JSZip.
Populate arrays just with one array element. You can add two different elements and JSON2Schema will create a oneOf-selector to the schema.
