How to reset form fields in a Word fillable form by adding an ActiveX command button that when a user clicks it, all of the form fields will be cleared out. Create a reset form button in Word that will work to clear both Legacy form fields and Content Control form fields. This button will uncheck a checked box, clear text from a text box and reset drop-down lists to the initial value. This Reset Form button will allow users to clear existing data that had been filled into the form so they can quickly and easily re-use the form like new. The Reset button is helpful when saving your form document as a Template file type will not support other features in the form.
