How can I have the submitted JotForm data reside in a downloadable attached text file instead of embedded in the email?

I want to save the form in my database system.  My form comes to me now embedded in the email, and I cannot save the data.  I do not want to cut and paste the data, I want to save the form.  I do not want to save the entire web page.  Can I do that somehow?

Just to confirm, when you said...

"I want to save the form in my database system.  My form comes to me now embedded in the email, and I cannot save the data.  I do not want to cut and paste the data"

...I'm assuming your end goal is to post your submission data to your own database. If so, then yes, that's doable but your database has to be MySQL and you will need to be knowledgeable with PHP programming. If you're not, you may relay these info to your developer(s).

Here's our complete guide on How-to-send-Submissions-to-Your-MySQL-Database-Using-PHP The general workflow is to:

1. Enable your form's option to Post Submission Data to the Thank You page.

2. Then create your PHP script to process the submission data and send it to your database.

On the other hand, you phrased your question as:

"How can I have the submitted JotForm data reside in a downloadable attached text file instead of embedded in the email?"

If all you need is a sort of a downloadable file that contains submission data, then just enable the PDF attachment option on your Email Notification. Just click EMAILS at the top > Email Notification (EDIT) > ADVANCED tab > toggle the PDF ATTACHMENT option to YES > then SAVE.
