Story of the xlCompare begins in 2009. First version has been published as a COM add-in for Microsoft Excel. It was able to compare Excel files and merge cells from one sheet to another. Unfortunately injection into Excel's model gives some important limitations. So, the complete independence of Microsoft Excel was just a matter of time.
2014
In 2014 new generation of xlCompare was published. This was a completely new software product, based on the Spreadsheet Core engine. It works much faster than COM add-in and got some features that are not possible in the Excel application. From this time xlCompare is constantly gets new features and improvements. xlCompare gets a command line interface (CLI) and ability to compare 3 files at once. This made it suitable for resolving editing conflicts with XLSX files in the GIT, SNV, Perforce and other version control applications.
