You can export the submission data in a .csv format from your submissions page, please check this guide:
If you need your submission data uploaded to an ftp server after the submitting the form, you can configure it from your forms submissions page too.
If you need your submitted data being uploaded in a .dat or .csv format just after submitting, you can configure the send post data attribute, the data will be posted to to your thank you page, in this case you will need to redirect your thank you page to a custom url, where your custom script will get the posted data and process it in order to achieve what you are looking for.
