What is a YAML Formatter?
A YAML formatter takes messy or minified YAML and restructures it with consistent indentation, making it readable at a glance. It also provides a minify option that strips away extra whitespace while preserving the document structure. The tool runs entirely in your browser, so your configuration files and data stay private.
How to Use
- Paste your YAML into the input panel. It can be a configuration file, a Kubernetes manifest, or any valid YAML document.
- Click "Format" to beautify the code with proper 2‑space indentation. Use "Minify" to remove blank lines and extra spaces, producing a compact version.
- Copy the result using the copy button, or click "Clear" to start fresh. The tool displays the byte size before and after the operation.
Frequently Asked Questions
Is my YAML data safe?
Absolutely. All processing happens locally in your browser. No data is ever sent to a server, stored, or logged. You can safely format sensitive configuration files or private data.
Does this tool work offline?
Yes, completely. There are no external libraries or network calls. Save the HTML file and you can format YAML anytime, even without an internet connection.
How accurate is the formatting?
The formatter uses a robust line‑by‑line algorithm that handles nested maps, lists, and comments. While it may not cover every edge case of the YAML spec, it works reliably for typical configuration and data files used in real‑world projects.
