What is the fastest way to delete all styles I manually put in a project?

What I am doing now is that I search for keywords like background or even a hash tag (#), double click the result and delete its style but the Table cells' styles are left out, not coming in search. I have to click each table cell to delete it. Thanks in advance PS : I am looking for a menu or command to include the table cells in search and later replacing their styles with classes.

This is a manual action, best practice is to always use classes. In that case you only have to adjust your stylesheet to make changes or disable styling.
