Good to know
A flat table cannot preserve every nested relationship. Array values can be kept as JSON, joined or ignored.
Frequently asked questions
Are commas and quotes escaped?
Yes. Cells containing delimiters, quotes or newlines are quoted using standard CSV escaping.
Why add a BOM?
Some Excel versions use a UTF-8 BOM to detect Chinese and other non-ASCII text.
