IIF File converter for QuickBooks Desktop

Hello, 

I am wondering if anyone has a suggestion for an IIF file converter for QuickBooks desktop. If our business was using QuickBooks online, services could be imported directly from Excel spreadsheet, however, QB desktop does not allow this. Our business uses Concur which has a built in IIF file converter but Procetive does not have that built in. Please provide a suggestion if you have found a product that works well or another solution that has worked. Currently the data is being entered manually, which is time intensive and introduces a certain amount of error. I appreciate your feedback.

Thanks,

Kim Marie
