Hello there, badarivaliveti.

We can export your QuickBooks Online data and then import them into Tally. Let me guide you how:

1. From the Gear icon, select Export data.
2. On the Reports and Lists tab, toggle the data that you want to export.
3. Click Export to Excel.
4. Click OK.

I've added this reference as your guide: Export Data out of QuickBooks Online.

I'm just a post-away if you have other concerns. Keep safe!
