YAML Tree Viewer
View YAML as an expandable tree to explore its structure.
Navigating YAML structure
YAML's indentation-based format is readable in the small, but a large configuration file is still hard to hold in your head — it is easy to lose track of how deeply something is nested or what belongs to what. Viewing it as a tree lets you expand and collapse sections, so you can navigate a big config, understand its structure, and drill down to the setting you need.
Paste your YAML and explore it as a tree.
Where the tree helps most
The tree view is especially useful for the sprawling configuration files that modern tooling produces — deployment configs, pipeline definitions, application settings — where the nesting runs deep and indentation alone stops being enough to follow. Collapsing the parts you do not care about isolates the part you do. It also makes YAML's structure unambiguous, which matters because a misplaced indent can quietly change what nests under what. Seeing the parsed tree confirms the structure is what you intended, catching indentation mistakes that are invisible in the raw text.
Frequently asked questions
How does a tree view help with YAML?
You expand and collapse sections to navigate deep configuration and drill down to a setting without losing track of the nesting.
Can it reveal indentation mistakes?
Yes — the parsed tree shows the real structure, so a misplaced indent that changed what nests where becomes visible.
Is my YAML uploaded?
No. It is parsed in your browser.
