To grep contents from a CSV/Text File using Autohotkey(AHK) Script - scripting

Question

Can anyone please help me in writing a script in AHK based on below requirement.
Requirement:
I have a CSV/TXT file in my windows environment which contains 20,000+ records in below format.
So, when I run the script it should prompt a InputBox to enter an instance name.
Example : If i enter Instance4 , it should display result in MsgBox as ServerName4
Sample Format:
ServerName1,ServerIP,Instance1,Type
ServerName2,ServerIP,Instance2,Type
ServerName3,ServerIP,Instance3,Type
ServerName4,ServerIP,Instance4,Type
ServerName5,ServerIP,Instance5,Type
.
.
.
Also as the CSV/TXT file contains large no of records , pls also consider the best way to avoid delay in fetching the results.

Please post your code, or at least show what you've already done.
You can use a Parsing Loop with CSV as the delimiter, and make a variable for each 'Instance' who's value is that of the current row's 'ServerName'.
The steps are to first FileRead the data from the file, then Loop, Parse like so:
Loop, Parse, data, CSV
{
; Parses row by row, then column by column in each row.
; A_LoopField // Current value
; A_Index // Current loop's index
; Write a script that makes a variable named with the current value of column 3, and give it the value of column 1
}
After that, you can make a Goto loop that spams InputBox and following a command that prints out the needed variable using the MsgBox command, like so:
MsgBox % %input%
