Add data to form via email

Add data to form via email

Hi,
I know that it is possible to email the form's data as email using input.formdata.

Similarly, is there any way by which i can add data to the form via email
(.. something similar to when we have excel sheet with same headings and upload it.. it automatically adds to the form's data)

Please advice,
Thank you,
REgards.
