YAML Formatting Guide

YAML formatting means applying consistent indentation, spacing, and structure to YAML documents. Well-formatted YAML is easier to read, maintain, and less prone to indentation errors that cause parsing failures.

What does a YAML formatter do?

A YAML formatter takes unformatted or poorly indented YAML and restructures it with consistent indentation, proper spacing, and clean formatting for better readability.

What indentation should I use for YAML?

The most common YAML indentation is 2 spaces. Some teams prefer 4 spaces. YAML does not allow tabs for indentation.

Will formatting change my YAML data?

No, formatting only changes whitespace and indentation. The data values remain exactly the same.

Is this tool free?

Yes, completely free with no signup or limits.
