What Edit and View YAML can do:

This tool acts as a lightweight YAML playground. You can freely paste, write, or edit YAML and get immediate feedback on whether it’s valid. It uses the js-yaml parser under the hood to catch syntax errors in real time. The editor also supports uploading .yaml, .yml, or .txt files, making it easy to review or tweak saved configs. It’s ideal for trying out changes before copying them back into production systems, testing small YAML blocks, or teaching new users how YAML structure works. No data leaves your browser everything happens locally.

Example:

Valid Input:

name: Alice
age: 30
skills:
  - Python
  - YAML

Validation Message:

Valid YAML ✔

Invalid Input Example:

name: Alice
age

Error Message:

[Invalid YAML] can not read a block mapping entry; a multiline key may not be an implicit key

Common Use Cases:

Use this tool to check or edit YAML configs for CI/CD pipelines, Kubernetes manifests, Ansible files, or static site generators. It’s quick, responsive, and perfect for reviewing syntax before pushing changes to production.

Useful Tools & Suggestions:

If you’re editing YAML directly in the browser, it’s helpful to Prettify YAML afterward so everything lines up cleanly. And when you’re done tweaking, Validate YAML makes sure nothing got accidentally broken along the way.
