Exporting Stock Financial Data into Excel

I would like to pull 3 attributes (Open, Close, Volume) for a variety of stock symbols. I would like to pull the stock data within a specific range and export it to an excel spreadsheet. I would also like to append the next stock ticker and its attributes to the bottom of the former.

So far I have the following code:

filename = "Data.xls"; data = FinancialData[    "GE", {"Open", "Close"}, {{2000, 1, 1}, {2021, 1, 1}}]; V = data // Normal; Export[filename, V]; 

Several problems are easy to see: Data for Open and Close are saving in separate tabs (I do not know why), adding additional ticker symbols forces all ticker data for a symbol into the same row in the same tab (again I do not know why), I am getting a string e.g.

Quantity[50.29999923706055, "USDollars"]

when all I want is the numerical piece. Finally, I am not getting the headers for each attribute as I am looking for.

I would really appreciate some assistance here. I have looked at other solutions as Creating a Stock Dataset but it doesn’t quite give me what I am looking for and my attempts to change it to meet my needs have failed.
