Multi line multi key label in header csv

[Manniac07]

I need to find a way to parse a csv file with metrics values based off of 2 headers.
Example:
csv file

TimeStamp,KeyLabel,SubKeyLabel,Metrics 1,Metrics 2,3 Metrics
1234567890,ABC,404 Not Found, 22,11,123
1234567890,ABC,ALL Good,33,12,321
1234567890,DEF,404 Not Found,44,18,456
1234567890,DEF,ALL Good,27,17,654

Results should be:

KeyLabel-"ABC",SubKeyLabel="404 Not Found", "Metrics 1 Value": "22"
KevLabel="ABC"
SubKeyLabel="404 Not Found'
"Metrics 2 Value": "11"
KeyLabel-"ABC", SubKeyLabel="404 Not Found"
1, "3
Metrics Value": 123"
KeyLabel-"ABC" ,SubKeyLabel-"ALL Good", "Metrics 1 Value™: 33" KeyLabel-"ABC", SubKeyLabel="ALL Good", "Metrics 2 Value": "12"
KeyLabel="ABC", SubKeyLabel-"ALL Good"
"3 Metrics Value": "321
KeyLabel-"DEF", SubKeyLabel="404 Not Found"
"Metrics
1 Value"« "дд
KeyLabel="DEF", SubKeyLabel="404 Not Found"
'Metrics 2 Value". 18
KeyLabel-"DEF", SubKeyLabel-"404 Not Found", "3 Metrics Value*: "456"
KeyLabel-"DEF", SubKeyLabel-"ALL Good"
"Metrics 1 Value": "27"
KeyLabel-"DEF',SubKeyLabel-"ALL Good", "Metrics 2 Value': 17" KeyLabel-"DEF", SubKeyLabel-"ALL Good", "3 Metrics Value: "654*
