Frequently Asked Questions
Common questions about Graphql Formatter formatting answered
Yes, our GraphQL formatter is completely free with no registration required. All processing happens in your browser.
Yes, our formatter supports formatting GraphQL queries, mutations, subscriptions, type definitions, and schema definitions.
Yes, the formatter properly handles fragment definitions, inline fragments, and fragment spreads with correct indentation.
No. The formatter only adjusts whitespace, indentation, and line breaks. The query structure and semantics remain identical.
Yes. During formatting, the parser checks for basic syntax errors like unclosed braces, invalid field names, and malformed arguments.
The GraphQL specification (spec.graphql.org, June 2018 working draft and its successors) - the same grammar graphql-js (the reference implementation) parses. Queries, mutations, subscriptions, fragment definitions, and SDL type system definitions all format against the spec's official style: 2-space indent, one field per line, arguments inline when short.
Named fragments (...UserFields) stay defined once at top level with on-type on its own line; inline fragments (... on Admin) keep the directive placement. Variable definitions ($limit: Int! = 10) align with canonical spacing - non-null ! glued tight, default values after =.
It validates syntax (the grammar must parse) but not schema conformance - that requires your server's schema, which a browser formatter deliberately does not fetch. Validation servers (Apollo, graphql-eslint) plug in at CI; the formatter's job is readable, spec-styled queries.
