# ParseJSON
<a name="API_ParseJSON"></a>

This processor parses log events that are in JSON format. It can extract JSON key-value pairs and place them under a destination that you specify.

Additionally, because you must have at least one parse-type processor in a transformer, you can use `ParseJSON` as that processor for JSON-format logs, so that you can also apply other processors, such as mutate processors, to these logs.

For more information about this processor including examples, see [ parseJSON](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CloudWatch-Logs-Transformation.html#CloudWatch-Logs-Transformation-parseJSON) in the *CloudWatch Logs User Guide*.
