# ParseCloudfront
This processor parses CloudFront vended logs, extract fields, and convert them into JSON format. Encoded field values are decoded. Values that are integers and doubles are treated as such. For more information about this processor including examples, see [ parseCloudfront](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CloudWatch-Logs-Transformation.html#CloudWatch-Logs-Transformation-parseCloudfront)
For more information about CloudFront log format, see [ Configure and use standard logs (access logs)](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html).
If you use this processor, it must be the first processor in your transformer.
