Can I use an excel sheet with checkboxes in the excel app for iPad?

I created an excel sheet for work that is a type of inspection sheet. The entire sheet is made with checkboxes(actual checkboxes inserted as objects with the developer in excel) to mark whether things are "in" or "out" of compliance. It was created to use on my iPad as I go from location to location; however, when I opened the sheet on my iPad with the free excel app, the checkboxes don't show up. Is there a way to fix this or are they unable to be used on an iPad?
