JSON to Go Struct Converter
Generate readable Go structs from JSON. Nested objects, arrays, nullable values, and JSON field tags are handled automatically.
✓ Go structs generated automatically in your browser
How to convert JSON to a Go struct
- Paste a representative JSON object or array.
- Choose the root struct and package names.
- Enable
omitemptywhen zero-value fields may be omitted during encoding. - Copy or download the generated Go source.
Review inferred types
JSON does not distinguish every Go numeric or domain type. The converter uses int for whole numbers and float64 for decimals. Review identifiers, numeric widths, timestamps, and validation requirements before integrating the result.
Frequently asked questions
How does JSON to Go type inference work?
The converter recursively maps JSON strings, integers, decimals, booleans, arrays, objects, and null values to Go types. Objects found in the same array are merged into one struct shape.
Why are some fields pointers?
A field becomes a pointer when the sample contains both a concrete scalar or struct value and null. This preserves the difference between a missing value and the type’s zero value.
Is the generated Go code ready for production?
It is a useful starting point. Review numeric widths, validation rules, custom time types, and domain-specific names before using generated structs in production.
Is my JSON uploaded?
No. JSON parsing and Go struct generation happen locally in your browser.
