YAML → CSV — readable configs to analyst grids

Great when observability YAML unwraps into uniform row shapes.

Developer notes

• If YAML parses to scalars, CSV export may be empty — reshape into tables. • Nested maps flatten with dotted headers like JSON exports.

When teams pick this route

• FinOps translating YAML price sheets into Sheets. • SRE snapshots needing spreadsheet filters.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Worked examples

Uniform list

Sample input

apiVersion: apps/v1
kind: Deployment
metadata:
  name: checkout-api
  labels:
    app: checkout
spec:
  replicas: 3
  selector:
    matchLabels:
      app: checkout
  template:
    metadata:
      labels:
        app: checkout
    spec:
      containers:
        - name: api
          image: registry.example/checkout:2.4.1
          ports:
            - containerPort: 8080

Sample output

apiVersion,kind,metadata.name,metadata.labels.app,spec.replicas,spec.selector.matchLabels.app,spec.template.metadata.labels.app,spec.template.spec.containers
apps/v1,Deployment,checkout-api,checkout,3,checkout,checkout,"{""name"":""api"",""image"":""registry.example/checkout:2.4.1"",""ports"":[{""containerPort"":8080}]}"

Wrapper unwrap

Sample input

service:
  name: billing-gateway
  port: 8443
  tls:
    enabled: true
    minVersion: "1.2"
  endpoints:
    - /health
    - /metrics
    - /ready

Sample output

name,port,endpoints,tls.enabled,tls.minVersion
billing-gateway,8443,"/health, /metrics, /ready",true,1.2

Flattening caveats

Mixed-type columns?

Everything becomes strings in CSV cells — cast downstream.

European delimiters?

Use Auto on /fr routes or pick semicolon explicitly.

Comments in YAML?

Comments vanish after JSON intermediate — capture them elsewhere.

Quoted commas inside cells?

Exporter handles RFC-style quoting per options.
