AWS CloudFormation Templates for Visual Studio Code

It works for both JSON and YAML templates, as long as the file extensions are respectively .cfn.json or .cfn.yaml. Alternatively, you can set the language mode for a file to "CloudFormation JSON" or "CloudFormation YAML" using the language picker in the bottom right.
