Select multiple answers didn't have commas in XLS

I tried to download the XLS file of the questionnaire results, but I found that the output of multiple-answer questions did not have commas separating one answer from another

Does anyone know how to get the commas separating each answer to appear?

@Kal_Lam can you help me, please?

Welcome @ykarimah,
Do you want to get the labels or the (choice) names?

I want to get the labels. Do you know something?

Welcome @ykarima,
There is no easy solution as multiple selects are stored internally as selected items separated by one blank.
Why do you need the comma?
