Hi Josh120,
You can run the Journal report in QuickBooks Online and export them as CSV file. Let's go to your reports tab to start with.
- Click on the Reports tab, search for Journal.
- Select a Report period.
- Click on More actions to view columns/filter you wanted to add to the report.
- Click on the Export/Print button and choose Export as CSV.
Another report you can run is Transaction List by Date. Repeat the same process when customising the report and exporting to CSV.
For a more detailed information, check this link for reference Print a journal entry report in QuickBooks Online.
Feel free to post again in the Community if you have other questions about running reports.
