YAML is text that uses indentation to show what belongs inside what. YAML Viewer turns it into a tree you can open one part at a time. It is for reading, not changing the file.
See what belongs under a name
Paste this into YAML:
service:
name: api
enabled: true
ports:
- 80
- 443
You should see service and ports in Tree. Open service to find name: api and enabled: true. Open ports to see its two list items, 80 and 443. The two-space indentation under service is why name and enabled appear inside it.
Change the indentation or remove a colon to see how structure or parsing can change. If the status shows an error, check the line it mentions before editing the rest. Parsed means the tool could read the YAML; it does not check whether service or ports are valid settings for your application.
This page processes the text in your browser. Configuration files can still contain secrets, so check a file before pasting its contents into a screenshot or sharing it elsewhere.
Where your input goes
Processing runs in your browser. The tool does not upload your input to ilham.dev.

Questions you might have
- Are YAML anchors expanded?
- Yes, which means the tree shows what the document means rather than how it was written. That is usually what you want, but it does hide where the reuse came from.
