Hello,

Try to remove all the older versions of poi-ooxml libraries from the userlib folder.

 

Hope it helps!

Hi, 


The latest versions of Excel importer/Excel exporter use POI 5.2.2.

Please delete all the jars related to POI, clean the deployment directory and download latest versions of Excel Exporter/Importer and Advanced Excel that are supported by your Mendix version.
