You can purchase a 3rd party service to convert data to Quicken but it will be expensive. I would recommend to convert your data to QB Desktop and use the trial version to access your historical data. Then you can start using Quicken from scratch.
We recognize the significance of efficiently exporting your QuickBooks Online (QBO) data to Quicken. Our aim is to assist you by offering several methods to accomplish this task.
While it is not currently possible to convert QBO data to Quicken (you can only convert Quicken data to QuickBooks), there is a positive alternative available. Let me share two alternatives with you on how you can successfully convert your QBO data to Quicken.
The initial option involves manually exporting your reports, lists, and other data from your account. Here's how to do it:
In QBO, go to the Settings (Gear icon) at the top right.
Click Export data.
On the Reports tab, set the date range.
Add or remove items from the Reports and Lists tabs by turning the switch on or off.
Once you have your data ready, the next step is to contact Quicken support for assistance with importing your data into their program. They will guide you through the process and ensure a smooth transition.
Another option is to use a third-party application that enables you to directly and efficiently convert your QBO data to Quicken. To find such an application, you can either navigate to the Apps menu within your QBO account or explore third-party apps outside of the QuickBooks website. This will provide you with a convenient solution for the conversion process.
