Format, prettify, and validate Azure Bicep template syntax.
Last verified: May 2026
Output will appear here...The formatter parses Bicep syntax (a custom DSL distinct from JSON), then re-serializes it with consistent indentation, aligned property colons, and standardized blank-line spacing between resources/modules/parameters. It validates basic syntax (proper braces, valid keywords) but does not perform full semantic checking — for that, use the Bicep CLI.
The Azure Bicep Formatter helps you format, prettify, and validate Azure Bicep template syntax directly in the browser. Bicep is Azure's domain-specific language for deploying resources declaratively, and consistent formatting is crucial for team collaboration. This tool applies proper indentation, aligns property blocks, and highlights syntax issues so you can fix them before compilation. It supports all current Bicep syntax including modules, decorators, and conditional deployments.
Your team is migrating from ARM JSON to Bicep. The Azure portal's `decompile` produces functional but ugly Bicep with inconsistent indentation and quirky property ordering. You paste the decompiled output into the formatter, get clean readable Bicep that matches your team's style guide, then commit. The formatted version sails through PR review and your team adopts the formatter as a standard pre-commit step for all Bicep work.
Bicep is dramatically more readable than ARM JSON for the same deployment — typically 50-70% fewer lines. If you're maintaining ARM templates in 2026, migration to Bicep is almost always the right move. Use `bicep decompile` to convert existing JSON templates as a starting point.
Bicep modules (separate .bicep files referenced via 'module' keyword) are the right abstraction unit, not nested templates. They compile to inline ARM templates but stay readable in source. For team-scale Azure deployments, organize resources into 1 module per logical layer (network, compute, data) rather than monolithic templates.
Bicep's type system catches many errors at compile time that would otherwise fail at deployment. Always run `bicep build` (or use VS Code with the extension) before deploying — it's much faster to catch a typo via the compiler than via 5-minute deployment rollback.
Azure Bicep is a domain-specific language (DSL) that simplifies authoring ARM templates. It compiles down to standard ARM JSON but offers a cleaner syntax with features like modules, loops, and conditions that make infrastructure-as-code more readable and maintainable.
No. This is a lightweight browser tool for quick formatting and syntax checks. For full compilation, deployment, and IntelliSense support, you should still use the Bicep CLI and VS Code extension in your development workflow.
