The GraphQL Formatter beautifies and minifies your GraphQL queries, mutations, and fragments. Unlike online formatters that log your code, our tool operates entirely in your browser — your queries never leave your machine. Whether you are cleaning up a messy query before code review, preparing schema documentation, or debugging a complex mutation, a well-formatted GraphQL query is much easier to read and maintain.
What is GraphQL Formatting?
GraphQL formatting applies consistent indentation, spacing, and line breaks. A well-formatted query lets you visualize data hierarchy and spot missing brackets at a glance. Minification removes unnecessary characters to reduce payload size — perfect for production optimization.
How to Use
- 1Paste your code: Enter your GraphQL query, mutation, or fragment into the editor.
- 2Choose style: Click "Beautify" for indentation or "Minify" to compress.
- 3Check stats: See the file size difference between original and result.
- 4Copy result: Grab the formatted code for your project or API client.
The Logic of the Formatter
The core is a recursive-descent parser. "Beautify" collapses extra spaces, identifies structural tokens, and applies correct indentation per nesting level. "Minify" strips comments and unnecessary whitespace using regular expressions — producing 100% valid, compact GraphQL.
Why Use This Tool
GraphQL queries can quickly become nested and hard to read, especially with multiple fields, arguments, and fragments. This formatter applies consistent indentation and line breaks, making your queries readable. The compact mode is useful for storing queries in databases or sharing them in space-constrained environments.
Tips for Developers
Use the beautify mode for code reviews and documentation. Use the minify mode to reduce query size for production storage. Always format before sharing GraphQL queries with teammates for clearer communication.
