Python convert Excel File (xls or xlsx) to/from ODS

Question

I've been scouring the net to find a Python library or tool that can converts an Excel file to/from ODS format, but haven't been able to come across anything.

I need the ability to input and output data in either format. We don't need to worry about merged cells, formulas or anything non-straightforward.

Answer 1

If you have libreoffice installed, you can do a python execution wrapper around its headless mode:

$ /usr/bin/libreoffice --headless --invisible -convert-to ods /home/cwgem/Downloads/QTL_Sample_data.xls 
convert /home/cwgem/Downloads/QTL_Sample_data.xls -> /home/cwgem/QTL_Sample_data.ods using OpenDocument Spreadsheet Flat XML
$ /usr/bin/libreoffice --headless --invisible -convert-to xls /home/cwgem/QTL_Sample_data.ods 
convert /home/cwgem/QTL_Sample_data.ods -> /home/cwgem/QTL_Sample_data.xls using

Which would be a bit easier than trying to do it through the library route.

Answer 2

I succeeded to convert an xlsx file to an ods file with this method:

1. install pyexcel-xlsx
2. install pyexcel-ods3

And use the following code:

from pyexcel_ods3 import save_data
from pyexcel_xlsx import get_data

dataXlsx = get_data("file.xlsx")
save_data("file.ods", dataXlsx)

Attention : the colors/design of the xlsx file is removed in the ouput ods file...so that it is not a real success.
