The best I found - and only - is from fx1.net called Excellink. Although not perfect, it allows you to read or write to and from from any cell in any sheet. Drawbacks? Only one workbook/file open at a time…
I am not attached/related to fx1, but am happily using their free products - of which they have quite a few. Sounds much better than paying EUR249 from this other advertised product.
