JSON to Go.

Pandia turns a JSON document into Go struct definitions with the matching json:"…" tags. Field names are converted to idiomatic exported Go casing (and common initialisms like ID are preserved) while the tags keep the original JSON keys.

Example

Input JSON:

{
  "id": 42,
  "name": "Ada",
  "active": true,
  "tags": ["admin", "early"]
}

Go output:

type Root struct {
	ID     int      `json:"id"`
	Name   string   `json:"name"`
	Active bool     `json:"active"`
	Tags   []string `json:"tags"`
}

What you get

• Exported struct fields with correct json:"…" tags.
• Idiomatic Go casing, with initialisms like ID and URL preserved.
• Nested objects and arrays become named structs and slices.
• Deterministic output — no options to tweak.

It’s the same engine behind Pandia’s type generation — opinionated, deterministic, and built to run on files far too large for an online converter.

Frequently asked questions

How do I generate Go structs from JSON?

Open the Types panel in Pandia, choose Go, and copy the generated structs — each with the JSON tags needed to unmarshal the original document.

Are JSON tags included?

Yes. Every field gets a json:"…" tag matching the original key, so encoding/json round-trips your data correctly.

Does it work offline and on large files?

Yes — everything runs locally with no upload, and Pandia opens multi-gigabyte JSON without lag.
