Open a YAML file and read its structure clearly, without an editor. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.
How to do it
- Drop your YAML file onto the box, or paste it.
- Read the structure below.
- Use the search box to find a value.
Questions
Which YAML features are supported?
Block mappings and sequences, flow collections, both quoting styles, block scalars and comments — which covers Docker Compose, GitHub Actions, Kubernetes and OpenAPI files. Anchors and aliases are named rather than guessed at.
Why does it say there is a tab in my file?
YAML does not allow tabs to indent. Expanding them to spaces would resolve your file’s nesting differently from every other reader, so it says so instead.
Is my file uploaded?
No. It is read in your browser and nowhere else.
