What the JSON to Go does
JSON to Go: converts Status and Go from JSON and Root struct name. Example: root struct name Root gives status 3 structs generated.
The inputs are JSON and Root struct name; the output is Status and Go. Change any input and the output follows immediately.
Reading raw machine output is painful; a formatted view makes the structure obvious. That is usually what brings anyone cleaning up machine output here.
The work is done by JavaScript already loaded in your browser, so your input never crosses the network.
The field reference, the method and a worked example using the default inputs follow the tool itself.
What do the JSON to Go fields mean?
The JSON to Go uses 2 inputs. Because the form arrives filled, the first useful result costs you zero typing.
| Field | What to enter | Default |
|---|---|---|
| JSON | paste or type any amount of text | { "id": 42, "name": "Ada", "is_active": true, "score": 9.5, "tags": ["admin", "dev"], "address": { "city": "London", "zip": "N1" }, "orders": [ { "id": 1, "total": 19.99 }, { "id": 2, "total": 5, "note": "gift" } ] } |
| Root struct name | required | Root |
How does the JSON to Go work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same conversion.
If something is off you are told which field, not given a generic failure.
Worked example
These are the values the JSON to Go loads by default, and the result it produces from them. Open the tool above and you will find precisely these figures already in place.
| JSON | { "id": 42, "name": "Ada", "is_active": true, "sc… |
|---|---|
| Root struct name | Root |
| Status | 3 structs generated |
|---|---|
| Go | package main type Root struct { ID int64 `json:"id"` Name string `json:"name"` IsActive bool… |
How to use it
- Paste your content into JSON.
- Fill in Root struct name.
- It runs on every change, so there is no moment where the screen is out of date.
- Read Status and Go in the results panel.
- Use Copy Link if you want the same setup again later, or Print for a paper copy.
What this tool does not do
- Processing happens in your browser, so very large inputs are bounded by available memory.
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- It handles the common case well and the unusual case literally.
Frequently asked questions
JSON and Root struct name, nothing else. Each field is pre-filled with a sensible default, so you can change one value at a time and watch how the result responds.
With the values loaded when the page opens, status comes out as 3 structs generated. Nudge one field at a time to see which one the answer is most sensitive to.
No. Nothing is uploaded: useful when the text you are inspecting contains keys or customer records.
