What the GraphQL Validator does
GraphQL Validator: checks Status and Report from GraphQL. Example: the sample loaded on the page gives status Structure looks OK.
Enter GraphQL and the GraphQL Validator reports Status and Report. Each change is reflected immediately, which suits quick what-if comparisons.
Spotting a malformed field is far quicker when the structure is laid out clearly. The GraphQL Validator exists to take that particular chore off your hands.
Everything happens inside this page. Nothing you type is sent to a server, and there is nothing for us to store.
The meaning of each field, the formula in use, and a worked example that starts from the default inputs are all further down.
What do the GraphQL Validator fields mean?
The GraphQL Validator uses 1 input. Every box starts with a working value, so there is a real result on screen before you touch anything.
| Field | What to enter | Default |
|---|---|---|
| GraphQL | paste or type any amount of text | query GetUser($id: ID!) { user(id: $id) { id name } } |
How does the GraphQL Validator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same check.
Nothing is computed until the inputs pass their checks, so you will not get a confident answer built on a typo.
Worked example
These are the values the GraphQL Validator loads by default, and the result it produces from them. The figures are the tool’s live defaults and its live output, so you can reproduce them exactly.
| GraphQL | query GetUser($id: ID!) { user(id: $id) { id na… |
|---|
| Status | Structure looks OK |
|---|---|
| Report | Basic GraphQL document structure OK. Use graphql.js parse() for full validation. |

How to use it
- Paste your content into GraphQL.
- The result appears as you type. There is no button to press.
- You get Status and Report back.
- The link encodes your inputs, so saving it is enough to reproduce the result later.
What this tool does not do
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- Processing happens in your browser, so very large inputs are bounded by available memory.
- The result reflects the moment you ran it; anything that changes over time is not tracked.
Frequently asked questions
Just GraphQL. Defaults are loaded for all of them, letting you treat it as a what-if tool rather than a data-entry form.
With the values loaded when the page opens, status comes out as Structure looks OK. That number tracks the inputs, so a small edit shows its sensitivity immediately.
Not at all: the whole thing runs offline once the page has loaded, which tells you nothing is being sent.
Free, and there is no upsell. The whole tool is the free version.
The output is deterministic. The same inputs always give the same answer, and the method is documented above so you can check it.
