Thank you for adding your first post, @ops11. It's my pleasure to help you with extracting your data correctly.

If I may ask, may I know what report you've exported? This way, I can gather enough information on why the debit and credit amounts behave that way.

 Usually, whatever data is showing up on your report, the same details should be displayed when exporting it to Excel. If your QuickBooks report has the Debit and Credit column, then the same columns will be extracted to Excel. Let me show you this screenshot as your visual reference.

For now, you can clear your browser cache before doing the process as stored files from your browser may affect this behaviour. Additionally, modify your report to narrow down the result. Here's how: Customise reports in QuickBooks Online.

For more tips, while handling your QBO reports in the future, check out the resources from this link: Setting up reports to customise, run, and share.

Let me know if you have any other questions while exporting your report or transactions to Excel. I'm always here to help. Keep safe!
