YAML is meant to be human-readable, but a long Kubernetes manifest or a multi-stage CI pipeline stops being readable somewhere around the third level of nesting, especially without colour. This YAML viewer highlights keys, values, and structure so you can follow indentation without counting spaces, and makes it obvious where one document ends and the next begins in a multi-document file. It is built for the reading task — checking what a pipeline actually does, seeing which values a manifest sets, or reviewing a config someone sent you — rather than editing. Paste the file and read it properly. Everything is parsed and rendered in your browser, so nothing is uploaded, which matters because YAML configuration so often contains internal hostnames, image references, and secrets.

Frequently asked questions

How do I view a YAML file without installing anything?

Paste the contents here. The document is highlighted immediately in your browser, with no upload and nothing to install.

Can I view Kubernetes manifests with several resources?

Yes. Multi-document YAML separated by --- is supported, so a manifest declaring several resources displays correctly.

Why is my YAML showing a parse error?

Most often a tab character used for indentation, inconsistent indentation between sibling keys, or an unquoted value containing a colon followed by a space.

Is my configuration uploaded?

No. Parsing and rendering happen entirely in your browser and nothing is transmitted or stored.

Can I edit the file here?

This tool is for reading. Use the YAML Editor to make changes, or the YAML Formatter to normalise indentation across a file.

How do I see the YAML as JSON instead?

Use the YAML to JSON converter, which is often the fastest way to understand an unfamiliar structure if you read JSON more fluently.
