GraphQL Query Formatter Online — Format GraphQL Queries Instantly

What is a GraphQL Query Formatter?

GraphQL is a query language and runtime for APIs that allows clients to request exactly the data they need. GraphQL queries can become complex quickly, with deeply nested selections, fragments, and variables.

A GraphQL formatter applies consistent indentation, line breaks, and spacing to transform messy, minified, or poorly formatted GraphQL into clean, readable code. This is essential for:

• Code Reviews: Readable queries are easier to review for correctness, security, and performance.
• Debugging: Formatted queries make it easier to spot syntax errors and understand nested structures.
• Documentation: Clean, formatted queries are essential for API documentation and developer onboarding.
• Team Consistency: Enforce consistent formatting across your team's GraphQL codebase.
• Logging and Monitoring: Formatted queries in logs are easier to analyze for debugging and performance tuning.

DevKits provides a free browser-based graphql query formatter online — your queries never leave your browser.
