I tried finally and it does not work. It produces the following error:

Traceback (most recent call last):
  File "/usr/bin/xlsx2csv", line 1129, in <module>
    xlsx2csv.convert(outfile, sheetid)
  File "/usr/bin/xlsx2csv", line 216, in convert
    self._convert(sheetid, outfile)
  File "/usr/bin/xlsx2csv", line 266, in _convert
    outfile = open(outfile, 'w+', encoding=self.options['outputencoding'], newline="")
io.UnsupportedOperation: File or stream is not seekable.

Bug reported upstream at https://github.com/dilshod/xlsx2csv/issues/213

I did try to add the Forwarded: pseudo-header, I hope it worked.

Thanks,

Sébastien.
