About this utility
How to use GraphQL Formatter & Operation Explorer
Format GraphQL documents, list operations and fragments, and check balanced syntax without executing a query.
What to provide
Paste a query, mutation, subscription, or SDL fragment. No GraphQL endpoint is contacted.
- Paste, type, or drag and drop a supported text file into the input area.
- Choose the options that match your intended result.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Readable GraphQL plus operation, variable, fragment, and depth summaries.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Schema-aware type validation, directive semantics, persisted-query hashes, and execution require a schema or server and are not performed.
