NoTag$():
include \masm32\MasmBasic\MasmBasic.inc ; download
Init
FileWrite "test.tab", NoTag$(Clip$()) ; get html from the clipboard, convert to plain text
ShEx "test.tab" ; launch the application associated with *.tab (often Excel)
EndOfCodeSource & exe attached. To test it,
- go to a site that has tables, e.g.
https://www.tiobe.com/tiobe-index/ or
http://masm32.com/board/index.php?action=stats- press Ctrl U to see the html source
- press Ctrl A, Ctrl C to copy the source
- launch the attached executable

WorldoMeters. Most Wikipedia tables should work, too - please inform me if you find one that doesn't. Note it will not work on sites that use scripts to generate tables, such as
this World Bank page.
The ancient Internet Explorer used to have the option to export a table; no idea why they abolished it
