There are two ways of exporting  your company files in QuickBooks Online (QBO), treehugger99. We’ll provide you with more details below.

If your subscription is QBO Advanced, you have the option to back up all your company data for future use through the Back up my company feature. However, for Simple Start, Essentials, and Plus, please note that this option is unavailable. You can check this resource for more details: Back up and restore your QuickBooks Online Advanced company.

Additionally, when backing up your Chart of accounts, you can manually export it outside QuickBooks as an Excel file.  This option is accessible regardless of the subscription you’re using. These are the steps:

1. Hover over Reports and open Standard reports.
2. Choose Account List from the report dropdown menu.
3. Click on the Columns section to choose the columns to display.
4. Once done, click the Export button.
5. Select Export to Excel .
