Free YAML Viewer — Interactive Tree Explorer
Paste any YAML document and explore it as a collapsible, syntax-colored tree instead of scanning raw indentation by eye. Expand and collapse nested mappings and sequences to focus on the part of the document you actually care about — ideal for digging through large config files, Kubernetes manifests, or CI pipeline definitions.
How to Use It
Paste your YAML into the left panel. It's parsed instantly and rendered as an interactive tree on the right — click the arrow next to any mapping or sequence to expand or collapse it.
Example
Pasting a nested document like settings:
debug: true
retries: 3 renders "settings" as a collapsible node — collapse it to hide the details, or expand it on its own to check just those two keys.
Common Use Cases
- Exploring a large, deeply nested Kubernetes manifest or CI config without scrolling through every line.
- Reviewing a YAML configuration file's structure before editing it.
- Collapsing irrelevant sections to focus on one part of a document during debugging.
- Getting a quick visual sense of a YAML document's shape and nesting depth.
FAQs
How is this different from the YAML Formatter?
The YAML Formatter focuses on re-indenting messy YAML text back into consistent, readable YAML. This viewer parses the YAML and renders it as an interactive, collapsible tree instead — the same exploration-focused interaction as our JSON Tree Viewer — so you can expand only the parts you need rather than reading reformatted text top to bottom.
Does it work with large YAML documents?
Yes — everything runs in your browser, and collapsing large branches you don't need makes it easy to navigate even sizeable documents without the page becoming sluggish.
Is my YAML data uploaded anywhere?
No — parsing and rendering happen entirely client-side in your browser. Your data is never sent to a server.
