It is realy easy to do using our form builder Excel import.

Your Excel file should be in the following format:

column name1 column name2 … column nameN

value1 value 2 … valueN

column name1 will be your form’s field with name ‘column name1’.
You can always rename it after importing your data without any data lost.

Create a form and click on the Import link.
Open your Excel file and copy all the content Ctrl + A → Ctrl + C
and paste to import the text area Ctrl + V
Press ‘Import’. You are done.
