About This Tool

The HCL Formatter online tool accepts HCL snippets used in Terraform and related HashiCorp products. It focuses on whitespace, indentation, brace alignment, and comment placement to produce a canonical, readable representation. The formatter preserves semantic content but standardizes style to avoid diffs caused by stylistic variations.
Core logic first parses input HCL into an AST, then applies a configurable set of rules: indentation size, max line length, and optional block sorting. It preserves comments and inline attributes while reflowing multi-line blocks. It reports any syntax issues encountered without altering the original content.
Audience includes DevOps engineers, Terraform practitioners, cloud architects, and code reviewers who value consistency across repositories. Unique differentiator is configurable formatting with safe defaults and explicit edge-case handling for nested blocks, quoted strings, and heredoc literals. Use cases include pre-commit formatting, code reviews, and onboarding new teams to a shared style.

How to Use

Provide inputs: paste HCL, adjust optional formatting settings like indent_size and max_line_length.
Run formatter: initiate the formatting process to generate formatted_hcl.
Review outputs: compare formatted_hcl to original; check formatting_rules_applied and any warnings.
Integrate: replace code in your Terraform configuration with the formatted version.
Validate: run terraform fmt -check or terraform validate to ensure semantic compatibility.

Frequently Asked Questions

Find Quick Answers

What is HCL?

HashiCorp Configuration Language is the language used by Terraform and other HashiCorp tools to define infrastructure. The formatter handles syntax structure, blocks, attributes, and strings, without evaluating resource semantics.

Does it verify semantics?

No. The tool focuses on syntax and layout. Semantic correctness, variable values, and provider behavior are outside its scope; use terraform validate and plan for those checks.

Can I customize formatting options?

Yes. You can configure indent_size, max_line_length, and optional block sorting or comment handling. Defaults align with common Terraform style guidelines.
