How to use

- Review the JSON output. The converted structure appears instantly in a readable format.
- Copy the JSON. Paste it into a tool, API, or workflow that expects JSON.
Common use cases
- Migrating Kubernetes manifests to JSON
- Converting CI and deployment config files
- Bridging YAML configs into JSON APIs
Frequently asked questions
- What is this YAML to JSON converter best for?
- Turning YAML config files into JSON when you need to inspect the structure, move data into JSON-based systems, or debug settings across tools that use different formats.
- Can I use it for Kubernetes or CI config files?
- Yes. It is a good fit for Kubernetes manifests, GitHub Actions and other CI files, deployment configs, and similar YAML-heavy workflows.
- Does this converter handle multi-document YAML (--- separators)?
- It converts the first document in a multi-document YAML stream. For multiple documents, split the file at the --- markers and convert each one individually.
- Are YAML anchors and aliases (&, *) supported?
- Yes. The js-yaml parser resolves anchors and merges them into the output JSON, so anchored values appear inline where they are referenced.
- Does this run in the browser?
- Yes. Conversion is local, which makes it convenient for quick format changes and safer for everyday config review work.
