.XLSX open not working after first attempt.

Question

I was able to succesfully open a .xlsx file one time, but now I always get the following:

This happens even on the file I originally successfully imported.  

I've tried uninstalling/installing yEd and forcing it to setup a new profile directory.  Nothing helps.

I am facing the same problem in yed. Need some help.

Answer 1

The columns for source ID and target ID have to be included in the data range! In your case neither column A nor column B is included in the data range from C1 to D1387. In short, change your data range to "Sheet1!A1:D1387".
