How to remove double quotes from an event field

[deev]

Please find the sample event field comment

comment="This is  sample data  "to remove the double quote value" how to remove it?It is for a  "testing purpose" which we need to handle "

I have tried

rex field=_raw  mode=sed "s/\"//g" 

But after that when we apply   table  command  |table comment , giving me partial data  "This is  sample data " 

Appreciate your help

Has the comment field already been extracted?

Can you share the complete _raw in a code block </>? (Obviously anonymising sensitive data first)
