Helm charts keep configuration in values.yaml and templates. The Kubernetes YAML to Helm Converter takes a plain manifest and produces that scaffold: a values.yaml with the parameterized values and a template where each field becomes a {{ .Values.* }} reference, so you can lift an existing manifest into a reusable chart.
Paste one manifest or a multi-document file. By default apiVersion and kind stay static while names, images, replicas and every other scalar become values. Array items such as containers use (index ...) references that map exactly to the values file.
Everything runs locally and nothing is uploaded.
