Bulk data extract replace double quote by 2 double quote

Hi Support Team,

I face the issue that when i create bulk extract lead data i saw that if  a data field is text or string and data contained double quote then when we extract and download the extract file, that field value will be replaced double quote with 2 double quote. Can you please take a look. Thank you

Ex: fristName field have value: john"test

But in my extract file it will be: john""test
