Hi, saurabhgupta.

In addition to Fiat Lux - ASIA's suggestion, you can explore the QuickBooks Online Apps menu to search for an application for importing data to integrate it with QuickBooks Online.

Here's how:

1. Go to the Apps menu from the left panel.
2. On the Search box, type "import". You can also click the Browser category button and select Sync data.
3. Review the app and check system requirements.
4. Select Get app now.

For detailed steps and an overview about importing data, you can reference this article: Move your Data into QuickBooks Online International.

Let me know if you have additional questions about getting your data to the platform. I'm always here t help. Have a good one.
