Import VAV parameters from from Excel file

I am trying to import the VAV parameters values from Excel file, but my problem is that I need to match the marks values to the already placed VAV marks parameters in Revit model and import additional parameter like “Actual Condenser Flow” and “Design Cooling Maximum Air Flow” etc. accordiginally but we are not solve this.
So please help with us.

You need to get the Mark value from your elements first, then either filter or sort your data to match. There are a ton of Excel import threads that deal with this exact same issue. You should be able to get some more direction from them if you need it. Try a few solutions and then let us know how it goes.
