Anyone know how to load data from desktop to online. The way they tell me don't work. There is another way that involves using like function and 2 letters?

Do you need to migrate data from QBD UD version to QBO US version? What do you mean with "functions and 2 letters"? Do you mean f2 key to get the product information of your QB Desktop file? Which QB Desktop year version do you have?

Good morning, @mark307. 

Congrats on making your first post here in the Community. Let's work together to get this problem handled. 

If you're needing to move your whole QuickBooks Desktop file to QuickBooks Online, here's a guide that provides details and instructions on how to do so:
