Project status

We're really busy at the moment (Jan 2018) and have put development of this on hold until we start to need it internally (which is likely to be a few months). If you're interested in using this, you have a few options:

NOTE: this is not yet ready to be used!


Power BI does not (currently) support integration with source control, which is a real pain, most notably because *.pbi{tx} cannot be diffed and merged. This means:

  • repos blow up quickly, as even with minor changes, the entire *.pbi{xt} is saved.
  • it's hard to collaborate as changes from two developers can't be merged, and hence changes must be made one after the other (so you're effectively limited to a single full-time developer per report).

This repo aims to improve this as much as possible (without tweaking Power BI itself) until Powe BI itself supports this.

That's right ... this is only a temporary hack, and should be treated as such.

It abuses the fact that *.pbi{tx} files are (nearly) just (double) ZIP compressed folders which follow a specific structure.

Installation [TODO]

Install python 3 (I recommend Anaconda if you're using Windows). Until someone writes the install script: just run the file

What do I get (currently)?

Say you've just made some changes to your Power BI file apples.pbix and you want to add it to version control. First, you'll need to export it as a Power BI Template i.e. apples.pbit, and then extract it into a VCS-friendly format:

pbivcs -x apples.pbit apples.pbit.vcs

will extract your apples.pbit into the VCS-friendly format at apples.pbit.vcs. If you choose, you can [TODO] automatically check that this will compress into a valid pbit. Then, for example

git commit -a -m "apples are so awesome"

will (assuming you've set it up as outlined below):

  1. [TODO] check you haven't accidentally forgotten to export a new pbit from your pbix
  2. commit apples.pbit.vcs to git
  3. (optionally) ignore apples.pbit and apples.pbix or [TODO] replace them with chksums (or a link to a file store of all versions? depending on your CI. TODO: can we actually create an apples.pbit.history folder to contain these? This would ensure no pbit is ever over-written.)

Now, suppose your colleague had also made a change to the same report. Then a git pull and git diff might show something like this:

-           "value": "Apples are yummy",
+           "value": "Apples are awesome",

and you can see that your colleague has just changed the title. There aren't any major conflicts, so you can happily git merge and merge your work.

You then want to make another change, so you need to compress the VCS-friendly format back to your pbit, which is as easy as

pbivcs -c apples.pbit.vcs apples.pbit

(and yes, since you're super careful, you can control how overwrites etc. happen).

Other cool features

  • TODO: change control: we'll attempt to keep this as up-to-date with Power BI as possible. The version of this tool that was used will be saved in any extraction/compression process, to allow (in theory) this tool to work on a complete git history, regardless of the Power BI versions used. (Provided this tool always functioned.)
  • TODO: everything's configurable to your level of comfort (e.g. always overwrite files, or check first, etc.)
  • lots of configuration. There a built-in defaults (conservative safe ones), but you can also specify your own defaults (in a hierarchy of .pbivcs.conf files), as well as utilising environment variables, and command line arguments. See below [TODO]

What don't I get?

  • unthinking automation (at least for now):
    • you still need to manually export a *.pbit from your *.pbix
    • you have to run scripts before/after the git actions. If this solution proves to be robust, we may automate this somewhat with git hooks or filters, but I'm wary of the bugs these may introduce into the user experience.


We use ConfigArgParse, which means pbivcs has the following configurations:

  • built-in defaults (which tend to be safe and conservative)
  • your own .pbivcs.conf files
  • environment variables
  • command line arguments

where each levels takes precedence over the one before. The main use is the .pbivcs.conf files which means you can customise it to behave as you want, without having to enter the options at the command line. The location of these files is such that they must be siblings of one of the elements on the path of you input file. E.g. if you run pbivcs -x /path/to/my/file.pbit then the following configuration files will be used (if they exist):

  • /.pbivcs.conf
  • /path/.pbivcs.conf
  • /path/to/.pbivcs.conf
  • /path/to/my/.pbivcs.conf

where each one takes precendence over the one preceeding it. Usually this would mean you would set a global .pbivcs.conf at the root of your project, but means you can have further ones in different parts of the project if you want different behaviour for the odd report.


  • figure out how to export *.pbit from *.pbix automatically
  • support other VCS ...
  • some git utility scripts e.g. to remove old *.pbix from repo and rebuild it as if we'd been using this tool the whole way along (i.e. replace *.pbit with the extracted version so we can hence track diffs)
  • automate git somewhat with hooks or filters




See ./

TODO (before 'release')

  • argparse etc.
  • provision script that sets up given repo: provide git template .gitignore and .gitattribtes (e.g. to ignore *.pbix or smudge them to a checksum, and ignore changed modifiedTime etc. in diffs.
  • tests ... how?
  • change control ... save version of tool used?
  • after compressing, test that the decompressed version is valid (by opening in Power BI Desktop)?
  • complete install instructions inc. conda environment


What about Power BI support?

Good question. Unfortunately, there are no indications of when this will be provided by Power BI.

What about git filters?

Sure you could do something like zippey. However, I think (?) this requires you to map a single file (*.pbit) to a single other file (in whatever format). While you could do something like in zippey (concatenating them all etc.) it'd start getting messy (especially with it still containing binary content e.g. images), and I'm not a fan. I also don't really like the idea of using automated filters (at least until I know more about how these are used in git).

Why not automate with git hooks?

Firstly, git hooks aren't shared between repos. Not a major, just saying.

Secondly, I don't know how things would behave in all situations. E.g. if you add the *.pbit and a hook runs to convert it to the VCS format. What then happens if you want to make a change to it? Anyway, if someone knows better, let me know (or submit a PR).


  • check that configargparse and use of config files behaves as expected
You can’t perform that action at this time.
