Terraform HCL Formatter

What Is HCL Sorting and Formatting?

The Terraform HCL Formatter goes beyond basic formatting by also sorting blocks alphabetically within your configuration. Well-organized Terraform code follows consistent conventions: resources are grouped and sorted, variables are listed alphabetically, and modules are organized in a predictable order. This tool applies two key transformations: formatting (indentation, alignment, whitespace) and sorting (block ordering for resources, variables, outputs, and modules). It helps teams maintain consistent code organization across projects, makes pull requests easier to review, and reduces merge conflicts. When enabled, the sort feature reorders blocks while preserving their internal structure, ensuring your configuration follows a logical, predictable arrangement.
