Can I make 2 different forms go on to the same spreadsheet?

I need different forms to go to the same spreadsheet. Is that possible?

There is a JotForm app that will allow you to combine submission data of up to 2 forms. 

The Combine Submissions App does this. 

The output data of the submission app is a CSV data file format. You can just import the CSV data into your spreadsheet using import function.

Alternative:

If you were using the Google Spreadsheet integration on your forms, the integration will create individual spreadsheet for each form/s that uses the integration.

What you may want to check instead is to consolidate each of the google spreadsheet data into a single/same spreadsheet. Google docs have this function called IMPORT Range which does the consolidation.

You can refer to this guide from Google docs.

Hope this help. Let us know how it goes.
