You can call the sub-workflow directly and do not need to use the JSON communication. A basic batch/cmd file might look like this: REM Set the path to your KNIME executable (Windows) set KNIME_PATH=C:\Users\%USERNAME%\software\knime_4.7.0\knime.exe REM Set the path to your workflow directory (the workflow you want to run) set WORKFL…
