About:
cfn-flip is a command-line utility that converts AWS CloudFormation templates between JSON and YAML formats. It intelligently handles intrinsic functions and outputs clean, readable YAML. This tool simplifies template management and promotes version control best practices.

Key Features:

Bidirectional JSON/YAML conversion
Preserves CloudFormation intrinsic functions
Outputs clean, human-readable YAML
Python-based for easy installation

Use Cases:

Migrating legacy JSON templates to modern YAML format
Preparing templates for version control systems
Converting templates for easier manual editing

Alternatives:

cfn-lint – cfn-lint validates templates but does not convert formats; cfn-flip focuses on conversion.
yq – yq is a general YAML processor, while cfn-flip is specifically aware of CloudFormation syntax.
