You should secure your data immediately and you can use an exporter tool. Then you may consider to purchase a 3rd party conversion service next month if required.

I'm pleased to see you, Raj. 

Let me share some information about data backup in QBO.

QuickBooks Online versions have an automatic backup feature since it's a cloud-based subscription. Every night, this procedure is carried out.

However, saving a backup copy of your file and restoring your data is unavailable. That said, I recommend utilizing our export feature to download data, reports, lists, and more from QuickBooks Online. For more details, please consider using this reference: Export your data from QuickBooks Online.

Otherwise, you may visit our QuickBooks App store and look for a third-party app that allows you to back up your entire file. Aside from that, you may also consider the suggestion of Fiat Lux - ASIA. 

Moreover, you can also customise your report and export it. It filters them to show specific accounts or customers or formats the layout so the right info shows up in the right place.

If I can be of assistance while working on managing your data in QuickBooks, please let me know. I'd be more than willing to lend you a hand. Keep safe.
