Convert JSON to Java Class without losing useful fields
Creates a plain Java class with public fields and common wrapper types inferred from the sample. Nested objects use Object so their structure is retained by typical JSON data binders.
Check the output before importing it
The converter reports invalid or unsupported input rather than guessing silently. Review the generated values in the destination application, especially date formats, nested data and identifiers that may have special meaning there.
