Struggling with messy GraphQL queries or schemas? Our free online GraphQL formatter instantly cleans and beautifies your code, making it easier to read, debug, and maintain with customizable indentation options.
Best Practice
Always use double quotes for strings in GraphQL arguments to stay compliant with the specification.
Did You Know?
GraphQL was created by Facebook in 2012 to solve the problem of data over-fetching on mobile devices.
GraphQL is a powerful query language for APIs and a runtime for fulfilling those queries with your existing data. Unlike traditional REST APIs, GraphQL allows clients to request exactly the data they need and nothing more. Because GraphQL relies heavily on a hierarchical structure of fields, arguments, and directives, maintaining a clean format is essential for understanding the relationship between data types and ensuring the API remains maintainable as it scales.
Tip
Keep your queries shallow; deeply nested GraphQL queries can lead to performance bottlenecks on the server.
While our online tool is perfect for quick fixes, you can automate this process in your daily development. Most developers use Prettier with a GraphQL plugin to handle formatting inside editors like VS Code or JetBrains. For teams, we recommend adding a linting step in your CI/CD pipeline using tools like graphql-eslint to ensure that every pull request adheres to your project's formatting standards before it is merged.
Q: Does this tool support GraphQL mutations and subscriptions? A: Yes, it supports all GraphQL operations including queries, mutations, subscriptions, and fragments.
Q: Can I format a full .graphqls schema file? A: Absolutely. The formatter is compatible with Schema Definition Language (SDL) used to define types and interfaces.
Q: Is there a limit to the size of the code I can paste? A: There is no strict limit, though extremely large schema files (several megabytes) may experience a slight delay during processing.
Q: Does it validate my GraphQL syntax? A: While primarily a formatter, the tool will often highlight structural issues that prevent the code from being beautified correctly.
