import data？

Where on the webpage can I import data? I didn't see any entry, so can I just add them one by one?

Start by inspecting the webpage's current data-entry flow and any existing import-related entry points. The issue does not name files, tests, supported data formats, or a desired import workflow, so clarify the intended behavior before implementation; done would require an agreed way to import data and verify that it appears in the application.
