Pls help.. Need to place orders from Excel to Nest Trader


I need a simple excel file to place orders on Nest trading platform.

The excel file will have few sheets, each sheet listing a set of orders.
The main sheet will have few buttons, each button assigned to a particular sheet
When pressing the button, the set of orders mentioned on the assigned sheet should be placed on Nest.

Though I can work on Excel, I do not know Excel VBA. Nor do I know how to connect Excel to Nest for placing orders. Kindly help me make this kind of an excel file, with clear instructions. Or even a template which allows modification would help.
