JSON to Go Struct
Generate Go structs with json tags from sample JSON instantly.

How to Generate Go Structs from JSON
Paste a sample JSON object or array and the tool generates Go struct definitions with json tags, PascalCase field names, and named nested types - ready to paste into your project for use with encoding/json.
Why Generate Structs from JSON?
Writing struct definitions by hand for a large API response is slow and error-prone - one typo in a json tag silently drops a field. Generating them from a real sample guarantees the shape matches the data.
Common Use Cases
Go developers generate structs when integrating third-party APIs, decoding webhook payloads, reading configuration files, and building typed clients for internal services.
Frequently Asked Questions
Are json struct tags included?
Yes. Every field gets a `json:"..."` tag with the original JSON key, so encoding/json marshals and unmarshals your data correctly even when Go field names differ.
How are nested objects handled?
Nested objects become their own named struct types referenced from the parent, so the generated code compiles as-is.
What types are inferred?
Whole numbers become int, decimals become float64, true/false become bool, text becomes string, and null or mixed arrays fall back to any.
Does my JSON leave the browser?
No. The generator runs entirely client-side, so internal API responses are safe to paste.
