About This Tool

The ARM JSON Formatter lets you format, prettify, and minify Azure Resource Manager template JSON directly in your browser. ARM templates can grow to hundreds or thousands of lines, and consistent formatting is essential for readability and code reviews. This tool auto-detects common ARM template structures and applies proper indentation, making nested resources, parameters, and outputs easy to scan. You can also minify templates for compact storage or inline use in deployment scripts.

When to Use This Tool

•Prettify a collapsed or minified ARM template before a code review to make resource definitions readable.
•Minify ARM template JSON to reduce file size when embedding templates in automation scripts or CI/CD payloads.
•Format ARM templates copied from Azure documentation or Stack Overflow answers into your project's coding style.
•Clean up machine-generated ARM export output from the Azure portal so it follows consistent indentation.
