Git XL:
A free and open-source local Git extension

NOTE: Git XL can be used independently of xltrail. Git XL allows you to work locally with VBA based workbooks, while xltrail is a web based application that allows you to work with both sheets and VBA. Git XL can be used with or without xltrail.

Git XL is a free & open-source Git extension that makes git diff and git merge work with Excel workbooks. It works either on the command line or with Atlassian's free Git desktop tool SourceTree, see here for an introduction.

xltrail works directly on the workbook file level and supports all Excel file formats, including xls, xlt, xla, xlam, xlsx, xlsm, xlsb, xltx, xltm.

Download v0.4.1 (Windows)

Getting Started

Download and install the Git extension by clicking the button above. You only have to set up Git XL once. Once downloaded and installed, set up Git XL by running:

C:\> git xl install

Alternatively, initialise Git XL per repository, using the --local option, inside the root folder of your repository's local working copy:

C:\Repository> git xl install --local

There is no step two.
Use git diff and git merge with workbook files, the same way as you normally do with text files.

Git XL is an open source project

To file an issue or contribute to the project, head over to the repository.
