GraphQL Schema Formatter

A GraphQL schema formatter is an essential tool for developers working with GraphQL APIs. It takes raw, unformatted schema definitions and transforms them into clean, consistently indented code that's easy to read and debug. Well-formatted schemas are crucial when collaborating with team members, reviewing API documentation, or migrating between different GraphQL implementations.

Simply paste your GraphQL schema definition into the input field and the tool automatically reformats it with proper indentation, line breaks, and spacing. It preserves all your type definitions, queries, mutations, subscriptions, and custom directives while organizing them in a standard, readable format. This is especially useful when you receive schemas from third-party APIs, export them from tools, or need to standardize formatting across your project.

The formatter works entirely in your browser—no data is sent to external servers, so your schema definitions remain private. It's helpful for developers of all levels, from those learning GraphQL to experienced architects managing complex multi-type systems. Whether you're reviewing Apollo schemas, Hasura exports, or custom implementations, properly formatted code reduces errors and makes onboarding new team members faster.
