When you are working with transformations, it is important to understand how file types map to one another and the transformation formats that each file type supports.
Transformations can cause OutOfMemory errors under certain conditions; for example, if you are using Excel (.xlsx) files that contain shapes or drawings (.xml content).
If you are experiencing OutOfMemory errors, set content.metadataExtracter.parseShapes=true in SkyVault-global.properties to ignore the xml content.
