Convert YAML to CSV Online
When your YAML data is a list of records — users, products, log entries — CSV is the format every spreadsheet, BI tool and data pipeline understands. This converter flattens a YAML sequence of objects into CSV with the headers in the first row. Nested fields collapse to dotted column names. Strings are properly quoted when they contain commas or newlines.

YAML vs CSV — what changes
Quick reference for the structural differences between both formats.
| Aspect | YAML | CSV |
|---|---|---|
| Shape | Hierarchical, nested. | Tabular, flat rows and columns. |
| Headers | Implicit in keys. | First row defines column names. |
| Types | Numbers, booleans, null distinguished. | Everything is a string — consumer parses on read. |
| Reuse | Anchors and aliases supported. | Every cell is independent. |
Frequently asked questions
What if my YAML is not a list of objects?
CSV needs uniform rows. If your YAML is a single object, the converter emits a two-column key/value CSV. For deeply nested data, flatten first or pick a different target format.
How are nested objects handled?
Nested keys flatten to dotted column names: address.city, address.zip. This keeps every record on one row.
Are commas inside strings escaped?
Yes. Values containing commas, double quotes or newlines are wrapped in double quotes, with internal quotes doubled per RFC 4180.
What delimiter does it use?
A comma. If you need tab-separated values (TSV) for Excel paste behavior, pick TSV as the output format in our format converter.
