GraphQL Workbench: complete usage guide
Format GraphQL queries, validate variables JSON, and inspect pasted introspection data locally before sharing API debugging notes or wiring a request into code.
What this tool does
It formats compact query, mutation, and fragment text into readable GraphQL structure.
It validates the variables pane as a JSON object and reports actionable parse or shape errors.
It extracts operation type, operation name, and type names from optional pasted introspection JSON.
It does not send GraphQL operations to an endpoint, so private queries and variables stay in the browser.
Typical use cases
- Clean a copied GraphQL operation before placing it in documentation or tests.
- Check variables JSON before pasting it into HTTP Request Builder or a client fixture.
- Inspect an introspection result that was already exported from a safe environment.
- Prepare API debugging evidence without contacting a production GraphQL endpoint.
- Normalize query formatting before comparing revisions in a pull request.
Input examples
Query
query GetUser($id: ID!) { user(id: $id) { id name email } }Variables
{
"id": "user_123"
}Output examples
Formatted query
query GetUser($id: ID!) {
user(id: $id) {
id
name
email
}
}Diagnostics
Operation: query GetUser
Variables: valid JSON object
Schema types: Query, User, Role
Common errors and fixes
Variables are valid JSON but not an object
Use a top-level object such as { "id": "user_123" }.
Mismatched braces or parentheses
Use the diagnostics and reduce the query to the smallest failing selection set.
Pasting live tokens into variables
Replace auth values and customer identifiers before formatting or sharing.
Security and privacy notes
For the shared privacy terminology, local processing model, external-request labels, and DevTools verification workflow, see the Trust Center.
- Formatting and diagnostics run locally without sending a GraphQL request.
- Pasted introspection JSON can reveal private schema names and should be treated as sensitive.
- Do not store production variables in saved notes or exported examples.
Step-by-step workflow
- Feed GraphQL Workbench the smallest reproducible sample you can collect from the real issue.
- Review the first findings and separate confirmed signals from assumptions or environment-specific noise.
- Compare a clean baseline sample against the problematic input when you need to isolate regressions.
- Keep one redacted output snapshot with the key findings for tickets, runbooks, or incident handoff.
Quality checklist before sharing output
- Confirm GraphQL Workbench findings still reproduce with the same input and assumptions.
- Check that the sample includes enough surrounding context to support the conclusion you are drawing.
- Translate notable findings into concrete next checks, ownership, or remediation notes.
- Redact private hosts, tokens, certificates, or customer identifiers before sharing analysis output.
Operational notes
GraphQL Workbench is most effective when it produces a focused, reproducible evidence bundle that can be handed to the next engineer without extra cleanup.
Frequently asked questions
Does this tool execute GraphQL requests?
No. It formats and inspects pasted text only.
Can it browse schema types?
It can summarize type names from pasted introspection JSON.
Does it validate against a live schema?
No. It performs local syntax and variables checks; live schema validation is intentionally not automatic.
