How does it work?
Paste raw, messy YAML into the left box. The tool re-indents each nested key onto its own line, normalizing the whole document to a consistent two-space indentation. Formatting happens instantly and entirely in your browser.
Example
Pasting irregularly indented YAML like settings:
debug: true
retries: 3 is cleaned up so debug and retries sit at the same consistent nesting level.
Common Use Cases
- Reading minified or poorly indented YAML configs (Docker, Kubernetes, CI pipelines).
- Cleaning up YAML you received before editing or sharing it.
- Standardizing indentation across config files to two spaces.
FAQs
Does this validate my YAML?
Not strictly. This uses a lightweight line-based re-indenter rather than a full YAML parser, so it focuses on consistent indentation rather than catching every syntax error.
Is my YAML uploaded anywhere?
No. Formatting happens entirely client-side — nothing you paste is sent to a server.
