You're saying it like there is no alternative and you can't just open and edit same excel files in Libre Office Calc, Google Sheets or Numbers without any problem whatsoever.

I'll say it too!

There's no serious alternative to Excel for those who rely on its advanced features.

You can't just edit Excel files in Libre Office Calc, Google Sheets, or Numbers without any problem whatsoever.

Not only is it about lack of features on the open source side, it's about workflow.

Sure Photoshop and Gimp both edit pictures, but the workflow is so different that professional users of Photoshop aren't going to switch just because it's FOSS.
