About YAML
YAML is an indentation-based format used for Kubernetes manifests, Docker Compose, GitHub Actions, OpenAPI specs and countless config files. It is a superset of JSON that favours readability.
About CSV
CSV (comma-separated values) is the universal format for spreadsheets and data exports. The first row holds column names and each following row is one record.
How it works
Nested objects are flattened into dot-separated column names (for example address.city) and arrays are written as JSON inside a cell. If your YAML wraps a list in an object, the list is used as the rows.
Private by design
Developer data is often sensitive: API responses, tokens, customer records, internal configs. This YAML to CSV processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.

Does the YAML to CSV conversion lose data?
Nested objects are flattened into dot-separated column names (for example address.city) and arrays are written as JSON inside a cell. If your YAML wraps a list in an object, the list is used as the rows.
