https://help.libreoffice.org/7.3/km/text/shared/guide/csv_params.html https://ask.libreoffice.org/t/how-to-convert-csv-from-command-line-and-ignore-first-lines/77114/ is how a user was confused that using the "Number of First Row" CSV filter token for export doesn't work. As Eike mentioned there, "the help text says “Row number to start reading” this is for importing CSV" - but there's an alternative reading of "start reading" as "read the spreadsheet when exporting". So having a uniform "CSV Import" marker, like those used starting from token 7, would be very clear. (I suppose that these markers deserve a separate column, so that token names are separate from import/export specifiers.)
Olivier Hallot committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/help/commit/44126837152e16fa861ded498f315d57b574e441 tdf#148943 Clarify CSV import token 4
