About GraphQL

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

Frequently Asked Questions

What is GraphQL formatting?

GraphQL formatting adds proper indentation, line breaks, and spacing to make GraphQL queries and schemas more readable. It transforms compressed GraphQL into a structured, easy-to-read format.

What does minifying GraphQL do?

Minifying GraphQL removes all unnecessary whitespace and line breaks to create the smallest possible query size. This reduces bandwidth usage when sending queries to GraphQL endpoints.

Is my GraphQL code safe to use with this tool?

Yes, this GraphQL formatter runs entirely in your browser. Your queries and schemas are never sent to our servers or stored anywhere. All processing happens locally on your device for maximum privacy and security.

Can I format both GraphQL queries and schemas?

Yes, this tool supports formatting both GraphQL queries (including mutations and subscriptions) and GraphQL schema definitions with proper indentation and structure.

What happens if my GraphQL has syntax errors?

The tool will attempt to format your GraphQL even with minor syntax errors. However, major syntax errors may prevent proper formatting and will be highlighted for you to fix.

What's the difference between GraphQL and REST APIs?

GraphQL allows clients to request exactly the data they need in a single query, while REST APIs typically require multiple requests to different endpoints. GraphQL also provides strong typing and introspection capabilities.

Do I need to install anything to use this tool?

No installation required! This is a web-based tool that works in any modern browser. Simply paste your GraphQL and start formatting immediately.
