Frequently Asked Questions
What is a GraphQL query formatter?
A GraphQL query formatter (also called a beautifier) takes unformatted or minified GraphQL syntax and rewrites it with consistent indentation and line breaks, making it easier to read, review, and debug.
Does this tool support mutations and subscriptions?
Yes. The formatter handles all standard GraphQL operation types: queries, mutations, subscriptions, and fragment definitions.
Is this tool free?
Completely free. No account, no login, no usage limit.
Are my queries stored or sent anywhere?
No. All formatting happens inside your browser using JavaScript. Your queries are never uploaded to any server.
Can I minify a GraphQL query too?
Yes. The tool includes a Minify button that strips all whitespace and compresses your query to a single line — useful for embedding in API calls or configuration files.
What happens if I paste invalid GraphQL?
The tool will highlight the parsing error and tell you where the syntax problem is so you can fix it before formatting.
What file extension does GraphQL use?
GraphQL files typically use the .graphql or .gql extension. The download button exports your formatted query as a .graphql file.
Can I use this for GraphQL schema SDL files?
The formatter is optimized for executable GraphQL operations (queries, mutations, etc.). It may handle simple SDL fragments, but a dedicated schema formatter is better for full SDL files.
