When I'm researching apps like yours, the thing I'm most curious about is the experience for my users. If you added a walkthrough showing the user experience for the top 3 most common problems people run into when importing data and how you address them in a usable way, you'd go a long way towards convincing me.
1) What happens if someone tries to upload a non-CSV file? What do you do?
2) What happens if the data is malformed or not in the right format or there are no headers at the top of the file?
3) How many steps does it take for someone to get from the uploading step to the final step? How do you make this easier?
