Terraform Formatter

# What Is Terraform HCL Formatting?

Terraform uses HashiCorp Configuration Language (HCL) to define infrastructure as code. HCL files contain blocks for resources, variables, outputs, data sources, providers, and modules. Proper formatting is essential for readability, code review, and team collaboration. This tool formats Terraform HCL configuration by applying consistent indentation, aligning assignment operators, organizing block structure, and normalizing whitespace. It performs similar functions to the built-in terraform fmt command but works entirely in the browser, making it convenient for quick formatting without installing Terraform. Developers use it to clean up messy configurations, enforce team coding standards, and prepare code for version control commits.

# How to Use This Tool

1. Paste your HCL code — Enter or paste Terraform configuration into the input area.
2. Click Format — The tool applies consistent indentation and alignment to the entire configuration.
3. Review the output — Formatted code is displayed in the output panel with a summary of lines, blocks, and changes.
4. Copy the result — Click Copy to copy the formatted HCL to your clipboard.
5. Use examples — Click the example buttons (Resource, Variables, Module, Messy) to see before-and-after formatting.
