Generate files and use csv data to replace multiple variables in a template

I have a source csv file consists of first field as variable name, and the rest are site-specific information (converted from excel file, where site -specific values in columns). I am trying to create a file for every site using a template and replace the multiple variables with values from the csv. I used sed but it takes too many find/replace substitutions. What is the best way to use in my script? Thanks in advance.

Sample csv:
---------------
Code:
$ cat multiple-replace-Book1.csv 
var_Site,SITE-A1,SITE-A2,SITE-A3,SITE-B1,SITE-B2,SITE-C2,SITE-C3,SITE-C4
var_Name,HOST-A1,HOST-A2,HOST-A3,HOST-B1,HOST-B2,HOST-C2,HOST-C3,HOST-C4
var_Ipaddress,11.11.11.1,11.11.11.2,11.11.11.3,22.22.22.1,22.22.22.3,33.33.33.1,33.33.33.2,33.33.33.3
var_Port,22,22,22,22,22,22,22,22
var_Location,Bay1,Bay5,Bay3,Bay1,Bay2,Bay4,Bay2,Bay3
var_City,London,London,London,Rome,Rome,Paris,Paris,Paris
var_Comment,Comment1,Comment2,Comment3,Comment4,Comment5,Comment6,Comment7,Comment8
var_Data,Data1,Data2,Data3,Data4,Data5,Data6,Data7,Data8
var_String,String1,String2,String3,String4,String5,String6,String7,String8

Template content:
-----------------------
Code:
Test connection to $var_Host from $var_Location in $var_City
Use $var_Ipaddress $var_Port to connect
Note: Apply this $var_Data and $var_String
Check: $var_Comment

Desired output file = $var_Site-file.txt
-------------------------
Code:
SITE-A1-file.txt (with site-A1 values)
SITE-A2-file.txt (with site-A2 values)
