WOW!!  That's hellza cool!!!  As I know, VBA doesn't work (AT ALL) with HTML, or any kind of online technologies.

Accrording to my search, you could not connect to SQL Server using Excel Online.
This issue is by design, so I suggest that you could submit feedback to Office.

Thanks, If I open Excel Online ... I see Data - Refresh Connections. Is there a way to know what this refresh connection is for? If not for SQL Server, what other connections are

Hi ihaveanazurequestion,

It's depending on how your environment is configured, some kinds of data connections are supported for workbooks displayed in a browser window, which enables you to refresh data. I suggest you refer to this article about refreshing data in a workbook in a browser window.

You also need to refer to this article about the difference between using a workbook in the browser and in Excel:

Hope it's helpful.
