Our Org Chart's answer:

Ability to create and edit org charts via csv, directly in chart, or via a table. If you have multiple charts you can pull up all of your employees across all of the charts and edit their details in one place. The org charts the employees are in update as well. It's also very easy to use and there's a Google Workspace add on. Plus, it was built by someone who spent several years in operations creating charts. There are extra features such as workforce planning and a process flow chart builder as well. Possibly the most important part is that it's free or very cheap.
