DiffEngineX is a useful utility that gives you a complete statistic on the differences between two Microsoft Excel workbooks. DiffEngineX is a utility that reports on the differences between the formulae and constants contained in either two whole Excel workbooks or selected worksheets. As Excel workbooks get modified over time new rows and columns can be inserted in between existing rows and columns.

This can confuse a straightforward difference analysis where identical cells are only recognized as such if they have the same row and column numbers in both of the sheets being compared. DiffEngineX can align both similar rows and columns between the worksheets being compared by the insertion of blank rows and columns. As such this problem is avoided.

Conventional reports listing each cell difference are difficult to understand given the lack of context. This is why there is an option to automatically create copies of the workbooks being compared and then modify them such that the differences are highlighted in color. Different colors are used to flag deletions, modifications and additions.

The options available allow users a choice between comparing formulae directly or by their calculated values. For example if two cells containing =2*6 and =3*4 are compared directly they will reported as different. If they are compared by their calculated values they will be reported as identical. It is common in workbooks modeling certain financial scenarios to have blocks of tens to hundreds of equivalent formulae that only differ from their neighbors in terms of their inputs.

The absolute coordinates of these inputs change from one cell to the next, but the relative coordinates do not. If a later version of such a workbook is compared to an earlier one, hundreds of changes can potentially be reported.

This makes a difference report tedious to inspect. DiffEngineX has a powerful feature to group equivalent changes made to contiguous cells into just one reported change made to a range of cells. It can be used from its user interface or the command prompt.

Features:

· Compare formulae & constants between workbooks or selected sheets
· Alignment of rows and/or columns with similar content between sheets (minimizes spurious differences)
· Difference report created in a new workbook
· Powerful option to highlight precisely the parts of formulae and text constants that differ on the report (=A1+Costs+6 and =A1+NewCosts+4)
· Color highlighting of differences, at the whole cell level, made to copies of your workbooks (separate colors for additions, deletions & modifications)
· Optional removal of existing workbook color before highlighting added (unconditional fill colour only)
· Choice of comparing formulae or their calculated values
· Report can group like changes if they are made to adjacent cells (report lists 1 change to a range of cells)
