This is a default of xlwt behaviour for writing Excel files.  It assumes it
would generally be an unintended mistake to write a cell then overwrite it
later with something else hence it by default raises an exception when this

Anyway, you can override this behaviour and enable cell overwriting by
adding the parameter "cell_overwrite_ok=True" when you create a worksheet.
However I think you probably are just accidentally (and erroneously)
overwriting the same row accidentally, so the error is probably meaningful
in your case.

Wahtever the case, I've taken the liberty to knock what you posted into
shape a bi -- The following script now works (well it finds files and
doesn't generate the error you reported.)  I've also tidied up the structure
and formatting as you'll see:


Hope that helps,
