YAML Viewer

beta

This free YAML viewer turns YAML into a collapsible tree so you can explore deep configs at a glance. It reads Kubernetes manifests, Docker Compose files, GitHub Actions workflows, OpenAPI specs and multi-document files separated by ---, with search and copyable paths. Your file never leaves your device.

How to use YAML Viewer

  1. 1 Paste YAML or load a .yaml/.yml file.
  2. 2 Expand or collapse sections, or use Expand all and Collapse all.
  3. 3 Search for a key or value to jump to it; matching sections open automatically.
  4. 4 Copy any value or its path. A syntax error shows the line and column to fix.

Frequently asked questions

Does it support multi-document YAML?

Yes. Files with several documents separated by --- are shown as a list, one entry per document.

Is my YAML file uploaded?

No. It is parsed and displayed entirely in your browser, so secrets in config files stay on your device.

Can I switch to JSON or TOML?

Yes. The same viewer reads JSON and TOML — use the format buttons, or load a file and the format is detected from its extension.
