About this tool
About this tool
GraphQL Formatter pretty-prints GraphQL queries and schemas by indenting fields, arguments, and nested selections with parsing that runs locally in your browser. Comments and operation names are preserved in formatted output.
Format GraphQL queries, mutations, fragments, and variables. Use the full-width workspace to format content while reviewing syntax, encodings, protocol fields, and implementation details. The tool accepts plain text, provides focused options, and creates GraphQL output that you can inspect, copy, download, or save as a local draft.

How to use this tool
How to use this tool
Configure the operation
Review the available processing controls. The selected controls determine how the GraphQL Formatter interprets the source and builds the result.
Run the tool
Start the GraphQL Formatter and review the result, visual preview, and technical report. Correct any reported issue and run the tool again when necessary.
Export or continue the workflow
Copy or download the GraphQL result, save a browser-local draft, or open a related tool for the next conversion, validation, or cleanup step.
Key features
Key features
Format queries, mutations, and fragments
Restructure GraphQL documents with consistent indentation so that fields, arguments, and nested selections are easy to read and navigate.
Argument and variable alignment
Align argument names and values, and format variable definitions with consistent spacing so that complex queries with many parameters remain legible.
Preserves GraphQL semantics
The formatter only changes whitespace and line breaks. Query logic, field names, types, and values are not altered.
Copy and download formatted output
One-click copy or download the reformatted GraphQL for pasting into a query editor, documentation, or version control.

Limitations and important notes
Limitations and important notes
- Formatting improves readability but does not guarantee semantic correctness.
- Large or deeply structured input depends on available browser memory and may process more slowly on mobile devices.
- The tool implements practical browser-based processing and may not reproduce every feature of specialist desktop software or every vendor-specific extension.
- Keep the original source and review generated output before production, security-sensitive, financial, legal, or safety-critical use.
Frequently asked questions
Frequently asked questions
It pretty-prints GraphQL queries and schemas by indenting fields, arguments, and nested selections with parsing that runs locally in your browser.
It formats for readability and preserves operation names and comments, but does not execute validation against a remote schema.
Local documents up to 25 MB are accepted, but parsing time grows with query depth and available device memory.
No. Formatting runs entirely on your device and never leaves the browser.
