OpenAPI / Swagger Spec Conversion
Convert OpenAPI 3.x or Swagger 2.0 API specifications between YAML and JSON. Both formats are valid and interchangeable.
Output will appear here…OpenAPI / Swagger tips
The OpenAPI spec supports both YAML and JSON. YAML is preferred for hand-written specs (more readable); JSON is preferred for programmatic generation.
Many code generators (e.g., openapi-generator-cli) accept both formats. Convert if your CI requires one specific format for consistency.
Swagger Hub and SwaggerUI render both formats identically. Conversion is useful when sharing specs with teams that have different format preferences.
Use the conversion to validate spec structure — YAML can hide schema issues that become obvious in JSON's explicit braces and quoted strings.
