GraphQL to Schema AST is a free online converter on AltFTool that parses GraphQL SDL into its Document AST as JSON, useful for tooling and analysis — no signup and nothing to install.
The conversion runs entirely in your browser: the GraphQL you paste is converted on your own device and is never uploaded to AltFTool. GraphQL to Schema AST is powered by the graphql library, and the Schema AST result can be copied or downloaded as graphql-to-schema-ast.json.
The input is a GraphQL schema written in SDL, not a query or a response, so paste the type definitions your server exposes.
| Input format | GraphQL |
|---|---|
| Output format | Schema AST (JSON syntax) |

Open GraphQL to Schema AST on AltFTool — the converter loads straight away, with no account.
Paste your GraphQL into the left-hand input pane, or press Sample to load a working example.
The conversion runs automatically about 300ms after you stop typing — there is no Convert button, and nothing is uploaded while it works.
If this converter exposes options, open Settings to change them — the output re-runs as you adjust.
Copy the Schema AST output with the Copy button, or download it as graphql-to-schema-ast.json.
No. GraphQL to Schema AST runs entirely in your browser using the graphql library, so the GraphQL you paste is converted on your own device and never reaches AltFTool's server.
The graphql library, running in your browser. The Schema AST you see is that library's output rather than an approximation written here.
There is no server-side limit, because nothing is uploaded — GraphQL to Schema AST converts in your browser, so the practical ceiling is your own device's memory.
The result is Schema AST. Copy it from the output pane in one click, or download it as graphql-to-schema-ast.json — AltFTool names the file after the converter and serves it as application/json.
Yes. GraphQL to Schema AST is free to use on AltFTool, with no account and no sign-up.
