What is a GraphQL Formatter / Validator?
A GraphQL Formatter / Validator formats GraphQL queries, mutations, subscriptions, fragments, and schema SDL into a consistent readable style.
It helps developers review GraphQL documents, catch syntax errors early, minify requests, and check basic structure such as operations, fragments, schema types, and selection depth.
How to use the GraphQL Formatter / Validator
- Paste a GraphQL query, mutation, fragment, or schema definition into the input editor.
- Click Format to pretty-print the document with consistent indentation.
- Click Validate to check syntax without changing the output.
- Review operations, fragments, types, depth, and validation notes.
Tips
- Use Format before code review to make GraphQL queries easier to scan.
- Use Minify when embedding a query in a compact request payload.
- High selection depth can make GraphQL resolvers more expensive.
- This tool validates syntax locally in your browser; it does not validate fields against a remote schema.

GraphQL Formatter / Validator FAQ
Can this validate GraphQL schema SDL?
Yes. You can paste schema definitions such as type, input, enum, interface, union, scalar, and directive documents.
Does it validate against my GraphQL server schema?
No. It validates GraphQL syntax locally, but it does not introspect a remote server or check whether fields exist.
Can it minify GraphQL?
Yes. It can remove comments and extra whitespace to create a compact GraphQL document.
Is my GraphQL document uploaded?
No. Formatting and validation run in your browser.
