DiffEngineX LLC distribute a software utility which reports on the differences between Microsoft Excel spreadsheets. In addition to comparing the actual workbook formulae and values, DiffEngineX compares the differences between Excel defined names, comments and the embedded Visual Basic for Applications (VBA) macros. DiffEngineX can ignore small numeric differences. DiffEngineX can compare database rows so long as they are first imported into Excel and pre-sorted. Excel has sort functionality under its Data tab. More details about DiffEngineX can be found at: http://www.florencesoft.com/compare-excel-workbooks-differences.html We have also developed a diff text tool called "Selection Diff Tool" that runs inside Microsoft Word and Excel 2013. At the moment it runs in the web version of Excel and hopefully soon will run in the web version of Word as soon as Microsoft launches the technology for Web Word apps. Our Office app can be obtained from: https://store.office.com/selection-diff-tool-WA103863850.aspx?assetid=WA103863850 We have also produced a free web-based diff text website.
