YAML to CSV Converter

How it works

How to use the YAML to CSV

1. Paste or open YAML

   Paste your YAML, drop a file onto the editor, or load the sample.

2. Adjust the options

   Nested objects are flattened into dotted columns such as address.city, and the first array of records in the document is used as the rows.

3. Copy or download the CSV

   The output updates as you type. Invalid input is highlighted with the exact line and column.

About YAML and CSV

YAML is a human-friendly superset of JSON that uses indentation instead of braces. It is the format of Kubernetes manifests, Docker Compose, GitHub Actions and most CI configs.

CSV (comma-separated values) is the lingua franca of spreadsheets and data exports: one record per line, fields separated by commas, quoted when needed (RFC 4180).

How the conversion works

Nested objects are flattened into dotted columns such as address.city, and the first array of records in the document is used as the rows. Conversion happens entirely in your browser, so even sensitive data never leaves your device.
