Add ternary operator in object

Question

I have to populate csv like, if val is there the in csv col colA it will add Val else add N
A+=[psobject]@(colA=Val: Val:N)
Can it be possible using powershell object A, it will reduce my effort to add else loop for value N as there are 128 colums also instead ternary operator is there any other way to print using hashtable or pscustomobject or any other way
