My newest app includes a java routine to read data from Excel 95, 97, 2000, XP, and 2003 workbooks and write the data into IRIS globals using Java Native API library.
If you have Git and Docker installed, clone/git pull the repo into any local directory
$ git clone https://github.com/oliverwilms/excel-java-iris.git
Open the terminal in this directory and run:
$ docker-compose up -d
Execute java class IRISNative
