Frequently Asked Questions
Getting Started
What is a GraphQL formatter?
A GraphQL formatter takes compact or unformatted GraphQL queries, mutations, subscriptions, and schemas and restructures them with consistent indentation, line breaks, and field ordering for better readability.
Is this GraphQL formatter free?
Yes. All tools are completely free and run locally in your browser. No signup, no limits, no hidden costs.
Does the tool store my queries?
No. Your GraphQL queries never leave your browser. All processing happens locally on your device, ensuring complete privacy and security.
Features & Usage
How do I format GraphQL?
Paste your GraphQL query into the input area and click "Format". You can toggle options for indent size, field sorting, and preserving description strings. The formatted output appears instantly in the right panel.
Does it support GraphQL schemas?
Yes. The formatter handles schema definition language (SDL) including type definitions, interfaces, enums, unions, input types, and directives with proper nesting.
Can I format both queries and mutations?
Yes. The formatter recognizes all GraphQL operations — queries, mutations, subscriptions — and formats each with appropriate structure and indentation.
Troubleshooting
What happens when Sort Fields is off?
With Sort Fields disabled, the formatter preserves the original field order. Indentation and line breaks are still applied normally.
Can I use this tool offline?
Yes! Once you've visited the page, all functionality works offline thanks to service workers and local processing.
