The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

The input is parsed at standard --- document markers, each YAML value is serialized independently, and the count reports how many stream items were found. Empty marker sections follow parser null-document behavior.

  • --- is the standard stream separator.
  • Independent output makes manifest files easier to copy.

Worked example

Split Kubernetes Service + Deployment
Split a multi-document K8s manifest file into individual YAML documents
Input
											---
apiVersion: v1
kind: Service
metadata:
  name: web
spec:
  ports:
    - port: 80
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: web
spec:
  replicas: 2
Output
												Documents: apiVersion: v1
kind: Service
metadata:
  name: web
spec:
  ports:
    - port: 80
, apiVersion: apps/v1
kind: Deployment
metadata:
  name: web
spec:
  replicas: 2

Count: 2

When to use this

kubectl manifests, deployment bundles, and sequential YAML streams split documents.

Edge cases

  • A --- inside a quoted scalar is data rather than a marker.
  • ... closes the current stream item.
  • An empty section can become a null document.
