How to Format GraphQL Queries - Step by Step Guide

Step 1

Input Your GraphQL Query or Schema

Let's get your GraphQL into the formatter! Whether you're working with Apollo Client, need to validate schemas, or want to minify queries later, you have several convenient options:

•
Paste directly: Copy your GraphQL query or schema and paste it into the input editor
•
Upload a file: Click "Upload" to select a .graphql or .gql file from your computer
•
Try the sample: Click "Sample" to load example data and see how the formatter works

Example: Unformatted GraphQL Query Input

Here's what messy, unformatted GraphQL looks like:

query{user(id:"123"){name email posts{title content comments{author message}}}}
Step 2

Automatic Formatting & Validation

The magic happens instantly! As soon as you input GraphQL, the formatter automatically:

•
Validates syntax: Checks for errors and highlights issues with helpful suggestions
•
Adds proper indentation: Makes nested queries and schema types easy to read
•
Syntax highlighting: Color-codes different elements for better readability

Example: Beautifully Formatted Output

The same query, now properly formatted and readable:

query {
  user(id: "123") {
    name
    email
    posts {
      title
      content
      comments {
        author
        message
      }
    }
  }
}
Step 3

Choose Format Options

Customize your output based on your needs! The formatter gives you control over how your GraphQL appears:

•
Pretty format: Default beautified GraphQL with proper indentation (2 spaces)
•
Minify option: Click "Minify" to compress GraphQL into a single line for production use
•
Syntax highlighting: Color-coded elements make it easy to spot queries, mutations, and fragments
Step 4

Export Your Formatted GraphQL

Get your perfectly formatted GraphQL ready for use! Multiple export options make it easy to integrate into your workflow:

•
Copy to clipboard: One-click copying for quick pasting into your code editor or application
•
Download as file: Save as a .graphql file for later use or sharing with your team
•
Real-time validation: Green checkmark confirms your GraphQL is valid and ready to use
