Can one change a form once it has been published?

We have a request from a client to remove a number of questions from a form they had approved and sent out.  If we did change the form, would it affect the database since they have already had responses?

Hi,

Yes you can edit a form anytime. However, remove fields with existing data will also remove it from the existing submission that form has.

Example case scenario:

1. The form has an "address" field and there are already submissions made.

2. You then decided to remove the address field, you'll get this message:

3. Here's the message:

The associated data that this is referring to is the existing submission data on that form. You can find your submission data by following this guide: https://www.jotform.com/help/269-How-to-View-Form-Submissions. Basically all the address data will be removed in your existing submissions. 

There are a number of ways on how you can handle this:

1. You can just clone the form and have the cloned form as a version 2 of your original form, the version 2 can be edited because it doesn't really have any submission data. Here's how you can clone your form: https://www.jotform.com/help/27-How-to-clone-an-existing-form-from-your-account 

2. You can backup your existing submission data by downloading them:

I hope that helps.
