1. Download the attached package RvlMerge.zip.
2. Unpack to some permanent folder.
3. Go to configuration of your source control UI and point to RvlMerge.exe as a merge tool for extension .xlsx.
The command line should look like:
C:\Temp\RvlMerge\RvlMerge.exe -s %theirs -d %merged
Some tools don't support selection of merge utility based on file extension. In this case we recommend to use the script SmartDiff.cmd, i.e.:
RvlMerge/SmartDiff.cmd %base %mine
You may edit SmartDiff.cmd and tweak it for your needs.
