If you have a set of completed forms and need to compile the data, you can use Acrobat to merge the responses into a single spreadsheet.
Start by putting all your completed PDF forms into a folder on your computer.
Open one of the completed form files, then select Prepare Form from the Tools center or right-hand pane.
Select More > Merge Data Files into Spreadsheet in the right-hand pane.
Select the folder you created with the completed forms.
Acrobat extracts the data from each form and creates a spreadsheet of all the data.
