GraphQL Query Formatter

Format GraphQL documents for review and debugging

Input and output check

GraphQL Query Formatter

Start from the sample input, then inspect the output panes, diagnostics, and structured mapping view before you copy any artifact into production tooling.

Diagnostics

Output details

Output review

Review these checks before copying generated output into a request, fixture, client, or support note.

Operation tree

Start with operation tree to confirm the workbench is modeling the same input surface you are debugging.

Variable inventory

The output pane keeps variable inventory visible so you can compare the raw input with the derived artifact.

Depth review

Use depth review as the final review pass before shipping the output into a terminal, database, or API client.

Output review rule

Scan nested fields, fragment boundaries, variable declarations, and max depth after formatting to catch overfetching or naming drift.

Sample input to try

Paste the exact compact GraphQL operation, including operation name, variables, aliases, and fragments from the client or persisted-query source.

Expected output review

Review the formatted operation tree for nested fields, variable declarations, fragment spreads, aliases, and depth before sharing or debugging it.

Real debugging sample
query OrderSummary($id: ID!){order(id:$id){id status customer{id email} items{sku quantity price} totals{subtotal tax grandTotal}}}
Common errors to check
  • Formatting an incomplete copied query that is missing fragment definitions.
  • Assuming formatting validates fields against the live schema.
  • Losing GraphQL string literal content while cleaning whitespace manually.
Next checks
  • Use GraphQL Query Minifier after the formatted query is reviewed.
  • Use API Request Builder to wrap the query, variables, endpoint, and headers.
  • Use JSON Formatter to inspect the variables object separately.
  • Use JSON Request Validator when variables need required-key checks.
Local processing: Formatting happens in the browser; query text and variables can still reveal internal type names, customer IDs, or unreleased fields.

Built for frontend engineers and API reviewers reformatting GraphQL operations before debugging or sharing them. Use this workbench for turning compact GraphQL documents into readable operation trees, then read the diagnostics before copying the artifact into a client, config, import job, or support note.

Request workflow and diagnostics

How The Workbench Is Structured

1. Raw input stays visible

The calculator keeps the original input close to the generated artifact so you can spot transformation drift before you copy anything forward.

2. Diagnostics sit beside output

Each tool pairs the generated output with concise warnings or checks so you do not need to interpret a raw string in isolation.

3. Mapping beats guesswork

The mapping panel highlights the pieces that matter for handoff: headers, query keys, columns, claims, chunk sizes, or file signatures.

The summary panel highlights the request, payload, token, or generated artifact that matters most for this workflow.

How To Use This Developer Workbench

Where GraphQL Query Formatter Fits In The Workflow

GraphQL Query Formatter is built for frontend engineers and API reviewers reformatting GraphQL operations before debugging or sharing them. The page treats the task as a workbench, not a single conversion box, so the output stays explainable when you hand it to another engineer or paste it into docs.

Inside API & HTTP, the focus is turning compact GraphQL documents into readable operation trees. That is why the page keeps the original input visible alongside the derived artifact and diagnostics.

  • Operation tree
  • Variable inventory
  • Depth review

How To Prepare Inputs

Paste the full operation including variable blocks and fragments so the formatter can preserve and inventory structure.

If you are debugging a live issue, start with the exact value captured from logs, docs, or traces before making cleanup edits. That makes the before-and-after result more trustworthy.

Checks Before You Ship The Result

Scan nested fields, fragment boundaries, variable declarations, and max depth after formatting to catch overfetching or naming drift.

Formatting improves readability but does not guarantee the document matches the live schema or resolver behavior.

Questions about this developer tool

What does GraphQL Query Formatter produce?

GraphQL Query Formatter is tuned for turning compact GraphQL documents into readable operation trees. The main output is a formatted GraphQL document, supported by diagnostics and a mapping view so you can review the transport or data shape before using it elsewhere.

What input shape works best for GraphQL Query Formatter?

Paste the full operation including variable blocks and fragments so the formatter can preserve and inventory structure.

What should I verify before using the output in production?

Scan nested fields, fragment boundaries, variable declarations, and max depth after formatting to catch overfetching or naming drift. Formatting improves readability but does not guarantee the document matches the live schema or resolver behavior.
