PIPELINE Data Transformation Intermediate 2 steps

Convert CSV to JSON then YAML

When turning a CSV of configuration rows into a YAML file for Kubernetes or CI pipelines, going through JSON gives you a reliable, inspectable intermediate. The first node converts CSV to a JSON array using the header row as keys; the second node converts that JSON to YAML.

What it solves

Transform spreadsheet CSV data into YAML via a JSON intermediate, suitable for config generation.
