Hi,
Thanks for the code - wondering if you have seen the following error message when try to open output file .... I use Excel2016 (Desktop) and also using Office 365 as well - both of keep saying "couldn't open your workbook. It's possibly corrupt or using a file format that's not supported"

Note - I use the CLI to generate the report per following (Running Python 3.6):
tech2xl.py GWSW.xlsm GWSW_show_tech.txt
tech2xl v1.5

Please let me know what you think.
Thanks,

I tried to attach the files here too.

Hi,
To be honest, I don't support too much this application. Apologize for that. Maybe it's an issue with the library that creates the Excel file. If you wish feel free to check and submit a PR if you find the solution!
