I'm here to lend a hand with importing a .QBW file into your QuickBooks Online (QBO) company file, @jtaylor-advanced.
To start, you'll need to open the .QBW file in QuickBooks Desktop (QBDT) and import the file from there. If you no longer have a version of QBDT installed on your computer, or it's an older version, you can use the trial version.
To help you with the process, you can check the below articles for guidance in restoring the file and how to move your company to QBO:
For future reference, I invite you to check this link which contains tutorials for the software: QuickBooks Tutorials since your importing to QBO. It can help to ensure that you get the most out of the software for your business.
Let me know if you have additional questions when importing @jtaylor-advanced. I'll be here to answer it for you. Have a good day.
