Form filling checkboxes

When filling a form from a csv file what is the correct way to code the selection of multiple checkboxes from a single column with multiple answers in the csv file?

Can you please post a website screenshot to clarify the situation?

So you want to read the checkbox status from a CSV file?

No. I want UI.Vision to fill out a webform from the answers I have in a csv file. The problem I have is I cant figure out how to properly code the json to select more than 1 checkbox in a given form field. How should this be done?
