Import Template for Item Number Changer Sage 300 ERP 2014

SOLVED

Does anyone have an Excel import template for the Item Number Changer that works?  I've created one based on the instructions in the Help File but it reports an "error reading worksheet file".  Years ago there was an issue with the Help File not listing the format correctly but the knowledgebase has no mention of this issue.

Any help greatly appreciated,

Dana
