About this Tool
Use this YAML to CSV Converter to turn readable YAML lists and objects into table-shaped CSV data. It parses YAML safely, detect row-like lists, flatten nested objects when useful, and export a CSV file with stable headers. The tool is best for configuration-like records, content lists, and small structured samples.
Examples
- tickets: - id: T-101 owner: Ada priority: high open: true - id: T-102 owner: Ben priority: normal open: false
Frequently Asked Questions
Are custom YAML tags executed?
No. YAML is parsed as data only. Custom tags, anchors, and comments may not survive conversion, and no user-provided code is executed.
How are nested JSON values handled?
Objects can be flattened with configurable path notation. Arrays work best when they contain row-like objects; deeply mixed arrays may need manual review before conversion.
How are data types detected?
Values can be inspected as strings first, then optionally detected as numbers, booleans, dates, or empty values. You can keep text mode when exact formatting matters.
Will YAML comments be preserved?
Usually not. Parsing YAML as data and exporting CSV focuses on values, so comments and original formatting are not guaranteed to survive.
