Formatting and Validating GraphQL Queries and Mutations

Messy, unindented GraphQL queries make code reviews difficult and hide syntax errors. Formatting queries according to standard GraphQL AST conventions ensures clean readability.

Format and validate your queries with the GraphQL Formatter & Validator.

Example: Formatted GraphQL Operation

query GetUserProfile($userId: ID!, $includeHistory: Boolean = false) {
  user(id: $userId) {
    id
    name
    email
    profilePicture(size: SMALL)
    orderHistory @include(if: $includeHistory) {
      id
      totalAmount
      createdAt
    }
  }
}

Validate syntax and prettify your GraphQL documents with the GraphQL Formatter & Validator.
