I want to export data from QB and import in Tally Prime. How can I do it?

It's great seeing you posting here in the Community, parth1. I've got details to share to help you import your QuickBooks data to Tally Prime.

When exporting data from QuickBooks Online (QBO), you can download all transactions, lists, reports, and attachments in an Excel file. You'll want to visit this article to learn more about how to get your data out from QuickBooks: Export Data out of QuickBooks Online.

Also, I'd suggest contacting Tally Prime to assist you in importing your QBO file to them. They can provide you with steps to ensure you're able to migrate your data. 

Additionally, you'll want to consider looking for a third-party application that helps you import your data from QuickBooks. You can follow these steps:

1. In your QBO account, go to the Apps menu.
2. Click on the Find Apps tab. 
3. Enter the search bar to look for an app.

There are also integrated applications that are available through the QuickBooks App Store.
