Live data into Excel

I may have finally learned the native way to get live numbers into Excel:

Can this also be used to publish numbers using Excel?

Excel to web and back again

The goal here is to learn to take a number in Excel and then automatically post it to a site on the web.

A second goal is to automatically read a number from the web.

This guy used VBA in word to call a Windows library.  So this solution is Windows only, but . . . maybe Excel is mostly Windows only anyway:

 A more general discussion is here:

From that discussion, one person used Querytables from VBA, which meant his solution worked for both Windows and Mac:

He also has a little bit to teach about going from the web to Google Docs and back.




But here's a more comprehensive resource if you're looking to learn about Google docs:

Might need to learn about Xpath for this.

It's also possible to link to a specific cell in Excel:
