Format GraphQL Queries & Schemas

GraphQL queries and schema definitions become difficult to read when minified or inconsistently formatted, especially in code reviews and documentation. This tool formats any GraphQL query, mutation, subscription, or SDL schema definition with consistent indentation and spacing according to the GraphQL specification. Paste your GraphQL and get clean, readable output immediately. The formatter also validates the syntax and reports errors so you can catch typos and structural issues before sending queries to a server. Everything runs client-side in your browser — your queries and schema never leave your machine.
