I wrote software professionally for 30 years. I have a good understanding of the work required to implement a business requirement! I cant really see myself spending 10 years on a one-week task :-)
PS. I didn't downvote you.
Why? You fetch data, calculate stuff and give out reports. Unless there is heavy javascript involved, you don't need a browser for any of this. But now you are dependent on the fragile setup you have created, hopping that VBScript, IE and your datasources will continue to work as long as you live.
Becoming independant and gaining a future ground would be a valid reason to change to a better environment. It doesn't need to be Python, but considering the requirements, Python is a very good choice for this it seems.
This is particularly true in the UK where there's a big push for "Open Banking" where banks must provide APIs for developers.
This would remove your dependency on IE if it was all done from the command line :)
