Python module for controlling LibreOffice programs (Writer, Calc, Impress, Draw, Math, and Base). Currently, manipulation of Calc instances is (somewhat) fully implemented and the module supports features such as:
[x] core functionality (open, save, close, ...)
[x] save multiple formats (ods, xlsx, ...)
[x] add/remove styles
[x] insert/delete/move sheets
[x] get/set values from a cell/range/rows/columns
[x] get/set cell/range properties (color, border, ...)
[x] merge/unmerge cells
[x] conditional formatting
Manipulation of Writer, Impress, Draw, and Math instances is in its early development and the module only allows for basic core functionality such as opening/closing/saving files. Base is not implemented at all and trying to open a LibreOffice Base instance will raise an error.
This module uses tmux to intermediate communication between a Python instance and the LibreOffice's internal python interpreter, which has free access to LibreOffice's Python API that allows controlling the LibreOffice components. This way, you are not limited to the functionality of LibreOffice's internal python, i.e., one is able to manipulate LibreOffice components from any Python terminal and inside Python environments. In addition to that, modifications to a file happen "real time" (no need to reload the file).
It was tested on:
- Linux (Ubuntu 20.04) and LibreOffice Version 7.0.4.2
and it should also work fine on MacOS. Currently, I don't think it will work on Windows since tmux is not implement there. However, it might work if one uses Windows Subsystem for Linux (WSL). I'm still trying to make it work.
DISCLAIMER: At first, this module was built to allow manipulating of Calc spreadsheets without the need to reload the document every time a modification was made. Since, this is done, I'm not sure I will keep working on it in order to extend the functionality to Writer, Impress, etc.. In any case, it should be easy enough to implement code for those since the core functionality is the same.
This module is heavily dependent on tmux which can be installed via apt-get on Debian or Ubuntu (check tmux page for installation instruction on other OS):
apt install tmux
The package libtmux (tmux workspace manager in python) is also necessary:
pip install libtmux
Lastly, some features for dealing with Calc instances uses numpy:
pip install numpy
Firstly, one has to start the office in Listening Mode. This can be done by opening the terminal and issuing the command:
soffice -accept=socket,host=0,port=8100;urp;
Alternatively, libreoffice-wrapper has a built-in function that starts LibreOffice in Listening Mode,
import libreoffice_wrapper as lw
pid = lw.start_soffice()Once LibreOffice is up and running in listening mode, one can now establish the communication,
soffice = lw.soffice()To close LibreOffice and its tmux session,
soffice.kill()Most functionality regarding Calc spreadsheets can be found in the example below,
import libreoffice_wrapper as lw
import time
# start LibreOffice and establish communication
pid = lw.start_soffice()
time.sleep(5)
soffice = lw.soffice()
# Open Calc
calc = soffice.Calc() # tries to connect with any open Calc instance
# If nothing is open, it will start a new spreadsheet
# calc = soffice.Calc('<path-to-spreadsheet-file>') # connects/opens specific file
# calc = soffice.Calc(force_new=True) # open a new file
# Calc info
print(calc.get_title())
print(calc.get_filepath())
print(calc.get_sheets_count())
print(calc.get_sheets_name())
# save
calc.save()
# calc.save('<path-to-save>')
# close Calc
# calc.close()
# insert new sheet
calc.insert_sheet('my_new_sheet')
