I need to import a bunch of journal entries from different dates by csv. file into quickbooks, but I can't find the button at the import data page.

Hello there, @circle-living. You can now import entries directly from the main Journal Entry page. Just go to + New or + Create > Journal entry -- Import. Before you begin, ensure that your file contains all the required details. If you're using any new accounts, remember to add them to your Chart of Accounts first so everything maps over smoothly. 

We'll be right here if you have other questions about managing your journal entries.
