What this tool does

YAML Viewer opens a YAML file and lays out its structure so the indentation-driven format becomes easy to read. See the keys, values, and nesting at a glance, which is exactly what you want when you are staring at a CI config, a Kubernetes manifest, or an app settings file.

How it works

Paste your YAML or open a file, and the viewer parses it in your browser and renders a clean, structured view. Read the nesting and spot where the indentation goes wrong. Nothing is uploaded.

When to use YAML Viewer

Reading a CI or pipeline config
Checking a Kubernetes or Docker Compose file
Reviewing app settings stored in YAML
Spotting an indentation mistake that breaks parsing
