JSON Formatter for Swagger / OpenAPI Definitions

Quick Answer: Paste your Swagger or OpenAPI spec JSON to format it. These definitions are often large with deeply nested paths, schemas, and parameters that become readable only when properly indented.

FAQ

Should I use JSON or YAML for OpenAPI specs?

Both are valid. YAML is more common for hand-editing, but JSON is what tools generate. This formatter handles the JSON format.

Can I format just a portion of my OpenAPI spec?

Yes. Copy any valid JSON fragment -- a single path object, a schema definition, or the components block -- and format it independently.
