I am using the tool to generate a .dmn file from the command line (linux):

$ java -jar kie-dmn-xls2dmn-cli-8.29.0.Final.jar ChScreening.xlsx
Using inputFile: /home/han/git/rivm/nhs/screening-business/src/main/resources/nhs-dmn/ChScreening.xlsx

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

Except for the message that I have no logging implementation, all seems ok. 

However, the columns are in the wrong order. This is the original table in the .xlsx file:

, and here  is the resulting table:

As you can see the content cells are transformed OK, however, the headers are messed up.

For diagnosis, I also added the .xlsx file as an attachment: ChScreening.zip
