Using xlCompare to compare and merge workbooks from the command line.
You can use xlCompare
from the Command Line. This feature allows you to integrate
xlCompare into external application.
For example, you can integrate it into the Version Control systems, like SVN.
To compare 2 files from the command line you should use the following syntax:
xlCompare.exe < path to first workbook > < path to second workbook >
Please note, usually you should specify full path to the xlCompare.exe utility. If xlCompare is installed into the default location, it
looks like this:
C:\Program Files\Spreadsheet Tools\xlCompare\xlCompare.exe
Or as another workaround you need to add folder path C:\Program Files\Spreadsheet Tools\xlCompare to the environment PATH variable.
