Thanks for posting in the Community forum, @sanapol.
Spreadsheet Sync allows you to sync Excel with your books in order to pull data into an Excel spreadsheet. You can edit spreadsheets in Excel and then post them back into QuickBooks. Using its list templates, you can also create custom reports and new data to enter into your books.
To ensure that you'll able to sync Excel file successfully, I recommend contacting our dedicated Spreadsheet Sync team. They can review the connection setup and help you get back on track.
To contact them, sign in to Spreadsheet Sync and go to Help, then Contact Us.
I've also included a couple of detailed resources about working with Spreadsheet Sync that may be useful in the future:
If you have additional questions about QuickBooks, let me know. I'll get back to you. Have a great day.
