Google Form Checkbox Separation

Hello all,

I recently created a survey in a google form with various checkbox questions. When I exported the results, all the checkbox questions are in on single cell, separated by a comma. Does anyone know if there is a macro or formula to separate these results into other columns? There are over 300 results so manually separating them is out. More than 1 row, rows g-r, need separation. And if there is a macro, can someone tell me how to implement it? Thanks!

(using a mac if relevant)
