JSON to Go Struct
Generate Go structs or a Root type alias with exported, unique field names and JSON tags. Mixed arrays and null use json.RawMessage; objects with keys that cannot be represented safely by struct tags use map[string]json.RawMessage.
About this json to go struct
JSON to Go Struct — browser-based utility.
How this tool works
Generate Go structs or a Root type alias with exported, unique field names and JSON tags. Mixed arrays and null use json.RawMessage; objects with keys that cannot be represented safely by struct tags use map[string]json.RawMessage.
- Paste one complete JSON value or load the sample.
- Run locally to generate code, then copy the complete result.
- Compile or validate the code in your target project and review inferred types before use.
Worked example
Scenario: Go: Generate a model for the displayed object and retain every original property.
Sample input:
Processing: Infer each value, emit the target declarations, then validate the original object using the target compiler or library.
Illustrative output:
Limits and verification
Accepts JSON text up to 1,000,000 UTF-16 code units and 100 nesting levels; output is limited to 8,388,608 code units. Invalid syntax, duplicate keys, invalid Unicode, unsafe integer values, overflow, underflow and decimal precision loss are rejected. Quote exact large numbers as strings. Dates remain strings. Inference describes the supplied sample, not every possible API response. Place the declarations in a Go package and decode JSON into Root with encoding/json. Integers use int64; decimal or exponent tokens use float64. RawMessage preserves untyped JSON but does not enforce its inferred shape. No BSON tags are generated; standard Go decoding permits unknown object fields.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
What exact Go Root struct does this page emit from the sample?+
Field names are Pascal-cased and keep original JSON names in tags. Heterogeneous values can require json.RawMessage rather than a precise struct field.
How are JSON names and value types represented in this Go Root struct?+
Exported Id, Name and Active fields with json tags and int64/bool/string types. Field names are Pascal-cased and keep original JSON names in tags. Heterogeneous values can require json.RawMessage rather than a precise struct field.
What inference boundary applies to Go Root struct output?+
The page emits text only; it does not run gofmt, compile Go, or prove that one sample covers future payloads.
Does Go Root struct generation execute or upload the generated language?+
Generation runs locally in the browser as text transformation; it does not execute, compile, or upload the generated Go Root struct. Ordinary page resource requests remain separate.
