How to add new submissions to excel report?

A couple of people have submitted their forms but the forms have not appeard on the XL report. As the system will only allow one go at registering is there any way of adding them manually to the report. Also I have deleted one submission in error, can it be re-established?

Could you provide a link to your form so we checked it closer? In general, you can download updated report from Submissions page: How-to-Download-Form-Submissions-as-Excel-CSV-PDF

If you would like to receive new submissions on excel sheet instantly, I can suggest to take a look at Google Sheets integration: How-to-Integrate-Forms-with-Google-Sheets

Unfortunately, we do not have an option to restore a submission if you have deleted it from Submissions page.
