Frequently Asked Questions
What does this GraphQL formatter do?▼
It takes minified or poorly formatted GraphQL queries and schemas, and reformats them with proper indentation and line breaks for improved readability. The formatted output is functionally identical to your input.
Does it validate my GraphQL syntax?▼
This tool focuses on formatting, not validation. It handles standard GraphQL syntax and produces well-formatted output. For syntax validation, use a dedicated GraphQL linter or your API playground.
Can I format GraphQL schemas, not just queries?▼
Yes. The formatter handles all GraphQL constructs including type definitions, input types, enums, interfaces, unions, and directives, in addition to queries, mutations, and subscriptions.
What indentation style does it use?▼
The formatter uses 2-space indentation by default, which is the most common convention in the GraphQL community. Each nesting level adds 2 additional spaces.
Does it handle GraphQL fragments?▼
Yes. Fragment definitions and fragment spreads (...FragmentName) are formatted correctly with proper indentation of their selection sets.
Can I format multiple queries at once?▼
You can paste multiple named operations (queries, mutations) in a single input and the formatter will handle them all, formatting each operation with proper spacing between them.
