GraphQL Query Formatter & Beautifier
Beautify, indent, and compress GraphQL queries, mutations, subscriptions, and fragment definitions.
What is the Online GraphQL Query Formatter & Beautifier?
The NexTools GraphQL Query Formatter is a specialized developer utility built to format, clean, and minify GraphQL documents. In modern web and mobile applications using Apollo Client, Relay, Urql, or direct HTTP POST requests, GraphQL operations often become flattened into single strings or embedded inside JavaScript template literals (gql`...`).
Our tool analyzes GraphQL tokens, nests selection sets hierarchically, aligns argument parentheses, cleans superfluous commas, and checks closing braces. It provides instant visual readability for auditing API calls, documentation examples, and debugging schema queries.
Key Capabilities of GraphQL Formatter
Hierarchical Field Nesting
Automatically nests subfields within nested object selections, producing standard 2-space or 4-space indentation.
Redundant Comma Stripping
In GraphQL specifications, commas are treated as insignificant whitespace. Our tool removes unneeded commas for clean modern syntax.
Single-Line Minification
Compresses complex queries down to minimal single-line strings, optimal for embedding into JSON POST bodies to reduce network overhead.
100% Client-Side Privacy
All formatting is executed directly in your browser. API queries, authorization headers, and schema mutations never touch an outside server.
Step-by-Step: How to Format GraphQL Queries
- Input your query: Paste your GraphQL query, mutation, or fragment into the left editor or load one of the preset samples.
- Select indentation options: Choose between 2 or 4 spaces and toggle automatic comma cleaning.
- Click "Format GraphQL": The tool structures the selection set and aligns arguments.
- Copy or Download: Click "Copy GraphQL" or "Download .graphql" to incorporate the formatted code into your project.
Frequently Asked Questions (FAQ)
Are commas required in GraphQL?
No. The GraphQL specification considers commas to be optional whitespace characters. While commas can be used between argument lists or fields, modern style guides (including Prettier) recommend omitting them for clean, idiomatic code.
Does this tool support GraphQL Fragments?
Yes. The formatter fully recognizes fragment FragmentName on TypeName { ... } definitions and formats them with identical nesting hierarchy.
Why should I minify GraphQL queries for production?
GraphQL queries sent over HTTP POST are transmitted inside a JSON body (e.g. {"query": "..."}). Minifying the query removes unnecessary line breaks and indent spaces, reducing payload weight on mobile networks.
What operation types can be formatted?
The tool formats all four primary GraphQL operation constructs: query, mutation, subscription, and fragment.
