JSON to Go

Turn a JSON sample into Go structs with json tags, nested types and nil-safe pointer fields.

Generate Go structs

Generated: —
Field names use Go initialisms, nested structs are named from the key path and optional fields become pointers with omitempty.

How to use the JSON to Go

  1. Paste a JSON sample and name the root struct.
  2. Press Generate structs to infer nested structs and tags.
  3. Copy the Go code into your package and unmarshal away.

Frequently Asked Questions

Common questions about the free online json to go.

Paste a JSON sample, name the root struct and press Generate structs to get Go types with json tags ready to paste.
Fields that are null or missing from some array items become pointers with omitempty, so absent values stay distinguishable from zero values.
Every nested object gets a struct named from the key path, so an address inside user becomes UserAddress.
Arrays are emitted as slices of the merged element type, including slices of nested structs.
Yes. Every field carries a json tag matching the original key, plus omitempty when the field is optional or nullable.
Keys are converted to exported Go names with common initialisms such as ID, URL and JSON applied automatically.
No. Parsing and code generation run entirely in your browser, so your data never leaves your device.
No. The output is plain text you can copy into any editor, and no Go installation is needed to generate it.
Yes. It is completely free, unlimited and needs no account or sign-up.
