Good day, commiepinko.
Let me assist you in exporting your data.
If you're using QuickBooks Desktop, you can convert your company file to QuickBooks Online. Just a heads up that there's a limitation when converting the file. Because of the feature differences, not all will be converted. Please check this link on what to expect when you switch from QuickBooks Desktop to QuickBooks Online.
For the detailed steps, you may check this article: Move your QuickBooks Desktop file to QuickBooks Online.
In addition, you can also manually bring in your data to QuickBooks Online. What we need is an Excel file that we can upload to your QuickBooks Online account. You can use either CSV (Comma Separated Values) or XLS/XLSX file formats.
Please check this guide in importing data to QuickBooks Online.
