export(row: list)

Called for each exported row. Row has been prepared and is a list, with values already converted if necessary. Rows are already reordered to match order of existing rows (if any), i.e. they match self._combined_headers (if defined).

export_headers(headers: list[Header])

Called at first exported row, if there are no pre-existing headers.

exported_count

Number of exported rows.

new_headers(headers: list[Header]) → bool | None

Called at first exported row, if there are headers that did not exist in pre-existing headers, and for dict rows having additional keys (if additional_headers is True).

Return None to prevent adding any new header, False to allow new columns but without a header name, and True to allow updating header names.

open() → list[Header] | None

Called at first exported row, before headers are analyzed.

Return list of existing headers, or None if file/headers must be created.
