These plugins enhance Excel's functionality, allowing multiple users to simultaneously edit workbooks, track changes in data ingestion processes, and maintain consistency between Excel files and their subsequent CSV formats used in databases. On this page, we'll delve into the essence of Git, explore the seamless integration provided by Git plugins for Excel, discuss common use cases where these plugins prove invaluable, and answer frequently asked questions. Enhance your team's productivity and data integrity with the insights gathered here.
What is Git?
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It is known for its tiny footprint and lightning-fast performance, offering features like cheap local branching, convenient staging areas, and compatibility with multiple workflows. Git is optimized to provide a command line interface and is capable of being a client for other systems as well as being embedded within them.
At its core, Git takes snapshots of a project's files, storing this information as a series of checkpoints or commits. Every commit records a picture of what all the project files look like at that moment. Each file and directory is checksummed using a 40-character SHA-1 hash before it is stored, ensuring the integrity of the version history. In Git, operations are performed locally, providing a robust framework that only adds data, thereby maintaining the history of changes in three states: modified, staged, and committed.
Git manages data as objects within the .git/objects directory. These objects come in three main types—blobs, trees, and commits—with each type having a unique header to specify its content. When a user runs commands like git add and git commit, Git stores blobs for the files that have changed, updates the index, writes out trees, and creates commit objects, all of which are kept in the .git/objects directory. Despite being stored in the same way, the content and header of each object type—blob, tree, and commit—are distinct from one another, reflecting the flexible and powerful nature of Git's data management.
Git Plugins for Excel
Using Git XL
Git XL is a free and open source local Git extension specifically designed to work with Excel workbooks. This plugin allows users to perform 'git diff' operations on Excel files, including those containing VBA code. To install Git XL, use the command 'git xl install'. For repository-specific initialization, use 'git xl install --local'.
Converting Excel Files to CSV
For tracking changes within Excel files using Git, files can be converted to CSV format. This can be accomplished by using third-party tools or writing custom scripts. One such tool that facilitates this by exporting Excel files to more Git-friendly formats is available at the GitHub repository 'https://github.com/stenci/ExcelToGit/tree/master'.
Writing a Custom Script
Alternatively, a custom Python script can be used to convert Excel files to CSV. This Python script needs to be specified in the .git/config and .gitattributes files of the Git repository to automate the conversion. The .gitattributes file requires the line '*.xls diff=xls', and the .git/config file should include the lines '[diff \"xlsx\"] textconv = python ./utils/xlsx_to_csv.py --input' to set up the custom diff operation for Excel files.
