How to diff Excel VBA code in SourceTree (Git client)

xltrail is a version control platform for Excel files and works similar like GitHub, BitBucket or GitLab with the difference that xltrail understands the content of Excel files.

While xltrail allows you to integrate with all of these Git providers, it also offers a free and open-source Git extension Git XL that allows you to diff and merge your VBA code locally either on the command line or most recently also through SourceTree.

You can download Git XL here. Note that you do not have to open an account to be able to use it. After clicking your way through the installer, you can activate the extension either globally for all repos (git xl install) or for specific repositories only (git xl install --local while being in a specific repo). For details see the instructions here.

If you now head over to your command line and run a Git diff command, it'll happily show you what changed in your VBA code:

Git Diff Cached

Basically, if I have just staged changes using git add, then a normal git diff won't show me those changes. It will only show me the changes that have not been staged. So, I add the --cached option:


Git Image Diff with iTerm2

This seems like it should be possible, you can replace what git does when you do a diff of two different binary files. For example, the spaceman-diff package by Zach Holman does this to do a diff of two images as ASCII art.
