DATMT Toolkit

OpenAPI/Swagger Extractor

Extract a subset of an OpenAPI 3.x or Swagger 2.0 specification by filtering paths. The tool automatically includes all referenced schemas recursively and preserves security schemes.

Path Filter

Server Override (optional)

Skip Fields (optional)

Use Regex

Input (OpenAPI/Swagger Spec - JSON or YAML)

Output (Extracted Subset - JSON)

Usage Tips

String Match: Enter a partial path like /pets to match all paths containing that string.
Regex Match: Enable "Use Regex" and enter patterns like ^/api/v1/ or /users|/orders.
Recursive: The tool automatically includes all schemas referenced by matched paths, including nested dependencies.
Security: Security schemes used by matched paths are preserved in the output.
