JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
So far we do not have an integration that will help you to send the submissions info directly to your Sharepoint site, if you would like you could capture the submitted data and sent it to your custom database or process it on your end, here's the guide that will help you with that: Send-POST-Data-From-JotForm-Using-PHP-in-Custom-Thank-You-Page
We have also some apps that will help you to export the data in the correct format and then you could simply import the data: https://apps.jotform.com/category/data_management
