What changes
| Avro to CSV | What happens |

| Codecs read | null, deflate, Snappy and Zstandard |
| Columns | The fields of the top-level record, in schema order |
| Nested values | Lists, maps and records become one cell of JSON text |
| Dates and times | ISO 8601: 2026-05-04 and 2026-05-04T08:00:00.000Z |
| Formulas | Cells that start with = + - or @ get a ' in front, so a spreadsheet shows them instead of running them |
