← All Tools
◈ GraphQL Formatter
Format GraphQL queries, mutations, fragments, and selection sets.
Why it is useful
It helps developers inspect generated queries, debug API calls, review fragments, and prepare documentation examples.
How it works
The browser reformats GraphQL text with consistent indentation and spacing.
Best input
Paste a query, mutation, fragment, or schema snippet that should be easier to read.
Debugging tip
Format first, then check variable names, fragment spreads, nested fields, and requested payload size.
Privacy note
Formatting happens locally in your browser.
Important limitation
Formatting does not validate permissions, resolver behavior, schema compatibility, or query cost.
Quick answers
Does it execute GraphQL?
No. It only formats text.
Can it format schemas?
Yes for many schema snippets, though dialect-specific syntax may vary.
Common Use Cases
Review a generated GraphQL query
Paste minified client output and format it before checking nested selections, fragments, and variables in a code review.
Prepare API documentation examples
Turn rough query snippets into readable examples for README files, docs pages, or support replies.
Debug resolver payload size
Format the query structure so large nested field requests and repeated fragment spreads are easier to spot.
