Read excel file

I’m modeling a retaining wall in Grasshopper. The Grasshopper script is connected to an excel file. I’m using the GHexcel inplug. How can I get grasshopper to read x number of rows by choosing the amount of rows in excel? You can see a picture of the excel here.

You can use Lunchbox excell reader / excell reader legacy (to read opened excell file)

But what when you want a live link? I have tried the Excel Dynamic Read component, but it keeps giving me errors that the object isnt set as an instance. Dont know what to do. Static read is possible but i dont prefer static read.
