How to enclose strings in quotes but ignore numbers?

[lxrco-sanjit]

Hello,

I was wondering how can I use custom enclosures per column. I am trying to generate a CSV file. The output should look like this

"string",2,"string"

I try to use the enclosure setting, but it either removes " from all the fields or none of them. Is there a way to add enclosures to strings only?
