Thanks for getting back with the Community, MariaMager.

I can certainly understand how an ability to import checks with an Excel file could be useful and have submitted a suggestion about it as of today.

You can also submit your own feature requests while signed in.

Here's how:

1. Use the Gear (⚙️) icon, then go to Feedback.
2. Enter your suggestion(s) in the Have feedback? window.
3. If necessary, attach a file with your Camera (📸) icon.
4. Select Next.
   

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.

For the time being, you can do as Mich_S suggested and review our QuickBooks App Store for apps which may be able to help you import checks using Excel files.

I've also included a detailed resource about importing data into QuickBooks which may come in handy moving forward: Common questions about importing data

I'll be here to help if there's any additional questions. Have a wonderful day!
