YAML Viewer
This YAML viewer renders a document as an interactive, collapsible tree. That matters more in YAML than in most formats: the structure is carried entirely by indentation, so a key sitting one level higher or lower than intended looks almost identical on the page but means something completely different. A tree makes the nesting explicit — you can see at a glance which parent a key actually belongs to instead of counting spaces. Filter by key or value to jump to what you need, and copy any row accessor path straight to your clipboard.
How it works
Renders the document as a collapsible tree, which makes the nesting explicit — useful in YAML, where indentation alone carries the structure and a misplaced key is easy to miss.
Filter to jump to a key or value, and copy any row’s accessor path straight to your clipboard.
Everything runs in your browser — nothing you paste is sent to a server.
The tree appears here once you paste a valid document.
How to view YAML as a tree
- Paste your YAML into the input on the left.
- The document renders as a collapsible tree, opened two levels deep.
- Filter by key or value, and copy any accessor path with the path button.
Why a tree helps with YAML specifically
In YAML the structure is carried entirely by indentation, so a key sitting one level higher or lower than intended looks almost identical on the page but means something completely different. A tree makes the nesting explicit — you can see at a glance which parent a key actually belongs to, rather than counting spaces.
Common use cases
- Auditing a long deployment manifest or CI pipeline definition.
- Confirming a key landed under the parent you meant.
- Finding a value buried several levels down and copying its path.
Frequently asked questions
Why view YAML as a tree?
Because YAML carries its structure in indentation alone, a key one level off looks nearly identical but means something else. A tree shows which parent each key actually belongs to instead of leaving you to count spaces.
How do I find a specific key?
Type into the filter box. Only the branches whose key or value matches are kept, and the path to each match is expanded automatically.
Can I copy the path to a value?
Yes. Hover a row and click the path button to copy its accessor path, ready to paste into code that reads the parsed document.
Are multi-document YAML files supported?
Yes. A file with several documents separated by --- is shown as a list, with each document as one entry in the tree.
Is my YAML uploaded when I view it?
No. Parsing and rendering happen entirely in your browser.
