Comma-separated values a spreadsheet opens with every character intact (since 0.18.0). The separator is the comma; a spreadsheet set to another list separator — Excel under a Spanish locale — asks for it on import. - The bytes are UTF-8 with a byte order mark, so Excel reads a ñ as one character. - Every field is quoted, with its quotes doubled, and every line ends in CRLF. - A field a spreadsheet would read as a formula is prefixed with an apostrophe, so it is shown and never run. That is any field beginning with one of OWASP's CSV-injection characters (`=`, `+`, `-`, `@`, tab, carriage return, line feed) or their full-width forms (`＝`, `＋`, `－`, `＠`). A product named `=HYPERLINK(…)` is text. A negative number becomes the text `'-5` as well, which is the price OWASP's own alternatives pay too. Every host that exports a list writes this. The guard is the part each copy got wrong, measured on the first one, which missed the line feed and the full-width forms.

the host's, as response/attachment says.

(write rows)rows, each a sequence of values (str of each, nil as empty), as the bytes of a
CSV file.
