What actually changes
NUMBERS and CSV are not the same picture in two wrappers.
The table cells are written out as delimited rows. Formulas become their computed values and all styling is discarded.
Worth knowing first
Because Numbers allows several tables on one sheet, the conversion has to decide what a row is. Tables are exported separately rather than merged, so a sheet with a summary table above a data table produces two files, not one.
Questions
NUMBERS to CSV, answered
Which table do I get?
Each one, separately. Merging them would produce rows with mismatched columns.
Do headers come through?
Numbers marks header rows explicitly, so they are preserved as the first row of the CSV.
