About YAML Formatter

YAML (YAML Ain't Markup Language) is a human-readable data serialization format widely used for configuration files, CI/CD pipelines, Kubernetes manifests, Docker Compose files, and infrastructure-as-code tools. Its indentation-based structure makes proper formatting critical for correctness.

Our YAML Formatter parses your YAML data, validates its structure, and outputs it with clean, consistent indentation. All processing happens entirely in your browser — your configuration data never leaves your machine. Use it to clean up messy YAML, validate syntax, or standardize indentation across your config files.

Frequently Asked Questions

What is a YAML Formatter? expand_more
A YAML Formatter is a tool that takes messy or inconsistently indented YAML data and restructures it with uniform indentation and clean formatting, making it easier to read and reducing the risk of indentation-related errors.
Does this tool validate YAML syntax? expand_more
Yes. The formatter parses your YAML data during formatting. If the YAML is invalid, it will display a clear error message indicating what went wrong and where the issue is.
Is my YAML data secure? expand_more
Yes. All processing happens locally in your browser using JavaScript. Your YAML data is never sent to any server, making it safe to use with sensitive configuration files.
Can I choose the indentation level? expand_more
Yes. Select between 2 spaces, 4 spaces, or tab-based indentation using the indent selector in the toolbar before formatting your YAML.
What does the Minify button do for YAML? expand_more
The Minify button converts your YAML to flow style (inline notation), which is more compact. This is useful for embedding YAML snippets in scripts or reducing file size.
