You don't have to worry if you only have the Online version, @mike304. You've got my back to help you resolve this.

You can use the Desktop trial version and from there. Before you start, make sure your computer meets the minimum requirements to install QuickBooks.

You just have to click the link you want to use. Save the install file somewhere you can easily find it, like your Windows Desktop.

From there, export your transactions to QuickBooks Online. Here's how: 

1. Sign up for any QuickBooks Online product that suits your business.
2. Set up your account by following the welcome interview process.
3. You can only import QuickBooks data within 60 days of your QuickBooks Online start date.
4. If you're using QuickBooks Desktop, migrate your file to QuickBooks Online. If you're unable to migrate your file, use Intuit's migration form and submit a copy of your file. If you're using another software, Odyssey can help migrate your file.
