Lens · yaml

See what your YAML actually says.

Indentation resolved into a tree, so you can see whether that key really is nested where you think it is. Multiple documents, block scalars, flow collections and anchors are all handled — and the same file can be viewed as JSON.

Files you open are remembered here, on this device, and are listed by every viewer. Nothing is sent anywhere — clearing them is permanent.

    Indentation, resolved

    The tree shows the structure the parser sees, which is the fastest way to find a key nested one level off.

    The awkward parts

    Multiple documents, | and > block scalars, inline flow collections, anchors, aliases and merge keys.

    Also as JSON

    Switch views to get the same data pretty-printed as JSON, ready to paste somewhere stricter.
