Frequently Asked Questions

What does the YAML Formatter do?

The YAML Formatter parses your YAML code and re-stringifies it with consistent two-space indentation. This ensures your YAML files have uniform formatting, making them easier to read and maintain.

Does the formatter change the content of my YAML?

The formatter normalizes indentation and applies type casting for values like booleans, numbers, and null. The structural meaning remains the same, but the formatting and some value representations may be standardized.

Can it handle complex YAML with nested structures?

Yes, the formatter supports nested objects, arrays, and mixed structures. It correctly handles indentation for deeply nested YAML, ensuring each level is properly aligned with two-space increments.

Is my YAML data sent to any server?

No. All formatting happens locally in your browser. Your YAML code is never uploaded or transmitted to any server, ensuring your data remains completely private and secure.

What happens if my YAML has syntax errors?

If the YAML cannot be parsed due to syntax errors, the tool displays an error message in the status bar. You will need to fix the syntax issues before the formatter can process your input successfully.
