JSON to Go Struct Converter — With Correct JSON Tags
Paste JSON to generate matching Go structs — exported field names converted to Go's PascalCase convention, correct types inferred, and the json: struct tags added automatically so the struct actually unmarshals the original field names correctly with encoding/json.
How to use JSON to Go
- Paste your JSON.
- Review the generated Go struct with json: tags.
- Copy it into your project.
Frequently asked questions
- Why does the struct need json: tags?
- Go's encoding/json package matches JSON keys to struct fields by name, but exported Go fields must be PascalCase — the json:"originalName" tag preserves the mapping back to your actual JSON field names, which are often camelCase or snake_case.
- Does it handle nested JSON objects?
- Yes — nested objects generate their own named struct type referenced from the parent struct.
- What about JSON fields with null values?
- Fields that can be null are typically generated as pointer types so the zero value and an explicit null/absent value are distinguishable.
