GraphQL Query Formatter
Expand minified query strings, normalize inline selection lists, compact argument blocks, and format fragments beautifully.
Dedicated In-Browser GraphQL Query Beautification
The GraphQL Query Formatter specializes in formatting complex operation queries, nested selection sets, fragment spreads, and variable definitions. When working with large enterprise GraphQL endpoints, query strings frequently become unwieldy with dozens of nested fields and inline fragments.
This utility analyzes GraphQL query grammar to produce clean, readable layout structures. It properly indents directive arguments (@include, @skip), aligns variable type signatures ($id: ID!), and formats nested sub-fields with consistent hierarchy.
Developers can configure tab or space widths, toggle fragment inlining, and copy formatted gql tagged template strings directly for Apollo Client and URQL. All formatting executes client-side with zero telemetry.
Core Tool Capabilities
- Deep Nested Selection Indentation: Maintains clean visual hierarchy across multi-level nested object relationships and connections.
- Directive and Argument Formatting: Aligns query parameters, variable declarations, and directives (@deprecated, @client, @include) cleanly.
- GQL Tagged Template Export: Wraps formatted queries inside JavaScript and TypeScript gql`...` tagged template strings ready for codebases.
- Real-Time Bracket Matching: Validates matching opening and closing curly braces, brackets, and parentheses to prevent syntax failures.

Frequently Asked Questions
- Can this tool format queries copied from browser network tabs?
- Yes. Single-line minified query strings from JSON request payloads are formatted into clean multi-line documents.
- Does the formatter support query variables ($var: String)?
- Yes. Variable definitions in the query header are properly aligned with their corresponding types and default values.
- Can I export the query wrapped in a gql template literal?
- Yes. You can export the output wrapped in a standard gql`...` tagged template literal for JavaScript and TypeScript.
- Are my query strings uploaded to remote servers?
- No. All lexical analysis and formatting occur entirely within your local browser memory.
- Does the tool modify query aliases or directive names?
- No. The formatter strictly adjusts whitespace and indentation, preserving all field aliases and directive names.
