Exporting OpenPlant file into Excel. Is PlantWise able to import Excel file as input?
You will have to consult the Wiki and the built-in Help section in order to find out how to import and if it's possible to import Excel files. I've searched various websites, but no dedicated instructions could be found. The best way is to access the built-in Help. Go to Search and simply type Import and then you will see all the available procedures and supported documents for Bentley PlantWise.
