Import from csv

I’ve seen a command line for exporting csv from .gan files : ‘ganttproject -export csv ./MyProjectFile.gan’ and it’s working fine.
I coudn’t find an ‘import’ command doing the opposite (importing csv into gan file). Is there any way to do that ? I need to automate the import process.

Is there a list of available command lines for ganttproject.exe? in github , on the web , locally on pc?
If there is no import command line, has someone managed to automate transform/export from csv to ganttproject with vba?

ganttproject -h will show you all available command line options. There is no command-line import, sorry.

thanks, ‘ganttproject -h’ is empty however

ganttproject.bat -h
