Is it possible to imbed an excel document with working formulas into a jot form?

You can embed Spreadsheets into your form.

Here is how:

1.) Insert an Iframe widget in your form.

2.) In your Spreadsheet get the Link URL to be pasted in your Iframe embed widget.

3.) Paste the Sheet URL in the Iframe embed widget.

Here is a sample form:https://form.jotform.co/82956525910867

Please give it a try and let us know if this fits your requirements.

Thank you.
