CSV lookup (multiple input, multiple output)

Elastic Stack Logstash
1

Hello. There is the way to lookup from file with multiple fields input and multiple fileds output?
For example:
I have csv like
field name field1 field2 field3 field4 field5
field data 1 2 3 4 5

And input data:
field name data1 data2 data3
field data 6 7 8

I want:
If field1.name == data1.name and field5.name == data3.name then
add_fields to data input: field2, field3, field4

Is it possible only by concating in one string? What are the ways to achieve this?
Thanks!
