Can the excel report list each item in a separate column by quantity/size?

Also, can the excel report list each item in a separate column by quantity/size? Right now, it comes in one big sentence in one cell. 

Unfortunately, it is not possible. If you are referring to the options or products listed in the payment field, then it is considered as one column. 

Noticed also that a product order will only show up in the column IF it is selected or the check box is ticked. Separating all of the items means all of the items must be selected before being downloaded as an excel file. 

The only way to separate them is for you to create a custom excel formula that would list and separate your items.
