I am trying to upload a file from my computer to QB. When I click on the "Upload the file" button, the screen goes blank and does not allow me to browse for the file?

"Upload the file" button? Did you try to convert data from another program to QB Online?

Hey there cindy_rae,

Welcome to the QuickBooks Community! Thanks for reaching out to us here. Being able to import files without running into any issues is important. I would be happy to provide some information.

It may be browsing data on your system that is preventing the software from doing what it is supposed to do. Here are some steps to resolve issues that are caused by browsing data:
 

• Clear your browser cache if you're using a browser
• Try a browser if you're using the app
• Try a private browser window
• Try another browser type
• Make sure you're using a supported browser and system
• Reset your Internet or try on another computer or device
• Uninstall the QuickBooks Online App, and re install it.

If you're still unable to upload your files, I recommend reaching out to the support team outside of the Community. They'll be able to verify your account details in a secure setting, as well as view your screen to better assist you. They also have the necessary tools to create a ticket to get the issue resolved if they see fit. You can reach them by following one of these methods:
