+description: The JSON Schema else conditional subschema, used with x-jsonschema-if when targeting OpenAPI versions that do not directly support it.
+schema:
+  $ref: "#/$defs/schemaObject"
+objects: [ "Schema Object" ]
+layout: default
+---
+
+{% capture summary %}
+The JSON Schema `else` keyword defines the subschema that applies when the `if` subschema does not match.
+
+The `x-jsonschema-else` extension mirrors the JSON Schema `else` keyword when targeting OpenAPI versions where the keyword is not directly available. It is serialized as `x-jsonschema-else` so tools can preserve and process the conditional subschema alongside `x-jsonschema-if`.
+
+It can appear as a property in the following objects: `{{page.objects|jsonify}}`.
+
+Used by: (informational)
+
+* [Microsoft.OpenApi](https://github.com/microsoft/OpenAPI.NET) (.NET OpenAPI library)
