The software directory website FindMySoft has produced a short video review on how to use DiffEngineX to find the differences between two Microsoft Excel spreadsheets. Their intention was not to create a full video review. Certainly we can see there is nothing in their video about Excel row alignment or pre-sorting Excel rows first (using Excel's Data tab), which is an issue that can catch some users out the first time they use DiffEngineX. (If you are comparing formulae based workbooks, you can ignore this extra step.)
