Frequently Asked Questions

AST (Abstract Syntax Tree) is the parsed structure of a GraphQL query. It represents operations, fields, arguments, and directives as a JSON tree that tools can analyze programmatically.

JSON representation helps analyze query complexity, build query tools, understand nested structures, or integrate with systems that need structured query data.

Operation type (query/mutation), name, variables, selection sets, field names, arguments, aliases, fragments, and directives are all captured in the JSON output.

Yes. Parsing happens entirely in your browser. No GraphQL queries are sent to any server. Your API structure remains confidential.

This tool focuses on operation documents (queries, mutations, subscriptions). Schema definitions use different AST structures.

Both fragment definitions and fragment spreads are parsed. Named fragments appear in the fragments section, spreads show where they're used.

Yes. Invalid GraphQL syntax produces parse errors. The tool shows where parsing failed to help debug malformed queries.

Yes. Copy the JSON output to use in scripts, query analyzers, or documentation generators. It's valid JSON ready for parsing.

Variable definitions include name, type, and default value if present. Variable usages in the query reference these definitions.
