Example: GraphQL Query Formatter and Validator
query GetUser($id:ID!){user(id:$id){id name}}
You add
GraphQL document: query GetUser($id: ID!) { user(id: $id) { id name } }
Indent spaces: 2
Line width: 80
You get
GraphQL grammar parsed and formatted.
Options
- Document
- Paste a query, mutation, subscription or other supported GraphQL document. Parsing concerns syntax and preserves the declared fields and variables.
- Indent and width
- Formatting choices control the downloaded source layout. They do not change the endpoint, variable values or permissions of an operation.
Supported inputs and limits
Up to 100,000 characters, 2,000 tokens and depth 100. Parsing/formatting uses the bundled Prettier GraphQL grammar. No schema validation, resolver execution, endpoint request or query-cost analysis.
Where your input is processed
This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.
A parsed query may still fail against a schema
Syntax can be valid while a field, argument or type is absent from the actual API. This page has no schema and makes no requests. Validate the operation against its intended schema, supply the required variables and review its effects before running it in another system. Formatting does not estimate query cost.
