To highlight a code snippet, follow these steps:

  1. Insert a new Text Box (Insert -> Text Box)
  2. Copy and paste/write your code snippet into the text box (You can choose any fonts based on your preference)
  3. Select the text box
  4. Go to Tools -> Highlight Code -> <Language of the code>

That's it. Your code should be colored based on the syntax.

I have tested only a few languages. If you find any bugs, please report them at GiHub Issues.

Note: This extension uses pygments to color the code. Pygments does not highlight some languages properly. Therefore, you may not get the best outcome for some languages. Sorry for the inconvenience.


Requirements (Close all LibreOffice products before installing these dependencies):

  • Python 3
  • python3-pygments
  • libreoffice-script-provider-python (May be optional)

Ubuntu and its derivatives users can install the dependencies using the following commands:

sudo apt install libreoffice-script-provider-python python3-pip
sudo pip3 install pygments

Windows users can install the dependencies using the following commands:

pip3 install pygments

Mac users can install it by following the instructions given at


Windows requires the environment variable: PYTHONPATH pointing to: C:\Users\<UserName>\AppData\Local\Programs\Python\Python<PythonVersion>\Lib\site-packages

You may face Scripting Framework error in your system. It happens if LibreOffice is using a different (most probably an internal package) Python. Please check the following Git Hub issues to resolve them.

    Phyton code seems to be broken.
    Installation of LibreOffice was done via
    My Version is: (x86)", line 1046, in getScript
    storageUri = self.provCtx.getStorageUrlFromPersistentUrl(
    File "C:\bin\PortableApps\LibreOfficePortable\App\libreoffice\program\", line 417, in getStorageUrlFromPersistentUrl
    package = self.mapPackageName2Path[ packageName ]

    Works very nicely! Not sure what all the fuss is about here. Simply install the dependencies, then go to the Github releases page, click the oxt file. This should open your LO application and install the extension. Worked flawlessly for me. (v1.6 with LO 7.x on Debian) I’m not to fond of the usability (once you have applied a style, it is not associated with the selected text), but that’s a different story.

    Worked perfectly for me after renaming it from edb...-whatever-....oxt to simply codehighlighter.oxt and then installing it after taking care of the dependencies

    Same as

    I had to remove the prefix in the installation file name to have it work as intended.
    Otherwise very good work !

    Thanks for you work !
    If, after installing the python package "pygments" (required by code-highlighter), you get the following error message when trying to run the add-on : "Message: <class 'ImportError'>: No module named 'pygments' ...", it may be because LibreOffice embeds its own version of python, independant of the one running on your system.
    In order to properly install pygments to the LibreOffice embedded version of python on linux, you can add it to the folder "/opt/libreofficeX.X/program/python-core-X.X.X/lib/site-packages" where the Xs depend the version of LibreOffice (and its embbeded python) you are running. There should be an equivalent fix for other OSs.

    Same with me. LibreOffice on Ubuntu, with OpenJDK-JRE and openoffice-java-common.
