add quotes to certain fields

I need to add double quotes to certain fields in a csv export.
WP All export add double quotes when there is a text with some words, but I need add double quotes in another fields.

For example, I have a line generated like this:

01/06/2018,7306,42,99.90,1,”This is a text”

And I need a line like this:

01/06/2018,”7306″,”42″,99.90,1,”This is a text”

Thank you very much in advance.
