While I don’t have any useful suggestions here… I thought I would link the thread I found in the xlwings github thread that the author looks to have been working on with them already.
https://github.com/xlwings/xlwings/issues/776 HTH Steven From: python-win32 <python-win32-bounces+steven=manross....@python.org> On Behalf Of Sébastien de Menten Sent: Wednesday, November 17, 2021 1:12 AM To: python-win32 <python-win32@python.org> Subject: [python-win32] returning #N/A to Excel via UDF I would like to return #N/A values to excel via an UDF written in python (via xlwings) Returning a `VARIANT(pythoncom.VT_ERROR, 2042)` from the UDF results in an empty cell. Is there within pywin32/pythoncom an equivalent of VBA `CVErr(xlErrNA)` ? Sébastien
