 The `write_json` processor converts an object in an event into a JSON string. You can customize the processor to choose the source and target field names.
 
-| Option | Description | Example |
-| :--- | :--- | :--- |
-| source | Mandatory field that specifies the name of the field in the event containing the message or object to be parsed. | If `source` is set to `"message"` and the input is `{"message": {"key1":"value1", "key2":{"key3":"value3"}}`, then the `write_json` processor generates `{"message": "{\"key1\":\"value`\", \"key2\":"{\"key3\":\"value3\"}"}"`.
-| target | An optional field that specifies the name of the field in which the resulting JSON string should be stored. If `target` is not specified, then the `source` field is used.
