What this formatter does

Adds line breaks around GraphQL-style braces and after commas, with two-space indentation for nested brace levels. It preserves ordinary quoted text and offers an immediate result that can be copied.

How to use it

Paste a query, mutation, fragment, or schema-like text and inspect the output. Reset clears the editor rather than restoring the sample.

Important limitations

This is a generic brace formatter, not a GraphQL parser, validator, schema checker, or canonical printer. It does not verify fields, variables, directives, types, or balanced syntax. GraphQL # comments are not recognized as comments, so newline collapsing can change what a comment covers; do not use it on documents containing # comments without a careful manual review. Block strings and unusual escapes also need checking.

How the brace scan works

The scanner reacts only to `{`, `}`, and `,` — it does not know that GraphQL uses `#` for comments, so a newline inserted after a comma can shift text that follows a `#` comment onto a different logical line than intended.

Example

Pasting `query{user(id:1){name,email}}` produces `query {` on its own line, an indented `user(id:1) {`, then `name,` and `email` each indented one level further, with matching closing braces at each level.

Safe review workflow

Run the formatted query through your GraphQL client or schema validator before relying on it, and manually re-check any document containing `#` comments since their scope can shift after reformatting.

Privacy

Formatting runs locally in your browser. Queries, schema text, and copied output are not uploaded by this tool.
