Click a node to expand/collapse. Hover any value and click the copy icon to copy it. Everything runs in your browser — your data is never uploaded.
Explore YAML as an interactive collapsible tree, free. A YAML viewer renders a YAML 1.2 document as an interactive, collapsible tree of mappings, sequences, and values so you can read nested config without tracking indentation by eye. This tool parses your YAML in the browser and lets you expand or collapse nodes, search, and copy any value on hover — entirely on your device.
It turns indentation-sensitive YAML into a clear, navigable tree with search and copy-on-hover, so you can verify structure without miscounting spaces. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Mappings and sequences become expandable nodes, so deeply nested YAML config is easy to drill into.
Filter the tree to jump straight to the setting you're looking for.
Hover any node to copy its value or subtree to the clipboard.
Your YAML is parsed locally; nothing is uploaded, logged, or stored.
It parses YAML and shows it as an interactive tree of mappings, sequences, and values, instead of raw indented text. That makes nested config far easier to read and verify than counting spaces.
Yes — YAML is indentation-sensitive, so the document must be correctly indented to parse. The viewer surfaces the resulting structure as a tree, which makes indentation mistakes obvious.
Yes. Parsing runs locally with no upload limit beyond your device's memory, and collapse/expand plus search keep large manifests navigable.
No. It's parsed entirely in your browser — safe for config that contains hostnames or other sensitive values.
Invalid indentation, tabs instead of spaces, or an unclosed quote will fail to parse. Fix the indentation (YAML forbids tabs for indentation), then view it.
