pyexcel-libxlsxw is a tiny wrapper library to write data in xlsx and xlsm format
using libxlsxwriter. You are likely to use it with pyexcel <https://github.com/pyexcel/pyexcel>__.
Support the project
If your company uses pyexcel and its components in a revenue-generating product,
please consider supporting the project on GitHub or
Patreon <https://www.patreon.com/bePatron?u=5537627>_. Your financial
support will enable me to dedicate more time to coding, improving documentation,
and creating engaging content.
Known constraints
Fonts, colors and charts are not supported.
Nor to read password protected xls, xlsx and ods files.
Installation
You can install pyexcel-libxlsxw via pip:
.. code-block:: bash
$ pip install pyexcel-libxlsxw
or clone it and install it:
.. code-block:: bash
$ git clone https://github.com/pyexcel/pyexcel-libxlsxw.git
$ cd pyexcel-libxlsxw
$ python setup.py install
Usage
As a standalone library
.. testcode:: :hide:
>>> import os
>>> import sys
>>> from io import BytesIO
>>> from collections import OrderedDict
Write to an xlsx file
Here's the sample code to write a dictionary to an xlsx file:
.. code-block:: python
>>> from pyexcel_libxlsxw import save_data
>>> data = OrderedDict() # from collections import OrderedDict
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [["row 1", "row 2", "row 3"]]})
>>> save_data("your_file.xlsx", data)
Here's the sample code to help you read the data back. You will need to install pyexcel-xls or pyexcel-xlsx.
.. code-block:: python
>>> from pyexcel_io import get_data
>>> data = get_data("your_file.xlsx")
>>> import json
>>> print(json.dumps(data))
{"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [["row 1", "row 2", "row 3"]]}
Write an xlsx to memory
Here's the sample code to write a dictionary to an xlsx file:
.. code-block:: python
>>> from pyexcel_libxlsxw import save_data
>>> data = OrderedDict()
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [[7, 8, 9], [10, 11, 12]]})
>>> io = BytesIO()
>>> save_data(io, data)
>>> # do something with the io
>>> # In reality, you might give it to your http response
>>> # object for downloading
Here's the sample code to help you read the data back. You will need to install pyexcel-xls or pyexcel-xlsx.
.. code-block:: python
>>> # This is just an illustration
>>> # In reality, you might deal with xlsx file upload
>>> # where you will read from requests.FILES['YOUR_XLSX_FILE']
>>> data = get_data(io, 'xlsx')
>>> print(json.dumps(data))
{"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [[7, 8, 9], [10, 11, 12]]}
As a pyexcel plugin
No longer, explicit import is needed since pyexcel version 0.2.2. Instead, this library is auto-loaded. So if you want to read data in xlsx format, installing it is enough.
Let's assume we have data as the following.
.. code-block:: python
>>> import pyexcel as pe
>>> sheet = pe.get_book(file_name="your_file.xlsx")
>>> sheet
Sheet 1:
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet 2:
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+
Writing to an xlsx file
Here is the sample code:
.. code-block:: python
>>> sheet.save_as("another_file.xlsx")

Developer guide
Development steps for code changes
#. git clone https://github.com/pyexcel/pyexcel-libxlsxw.git #. cd pyexcel-libxlsxw
Upgrade your setup tools and pip. They are needed for development and testing only:
#. pip install --upgrade setuptools pip
Then install relevant development requirements:
#. pip install -r rnd_requirements.txt # if such a file exists #. pip install -r requirements.txt #. pip install -r tests/requirements.txt
Once you have finished your changes, please provide test case(s), relevant documentation and update changelog.yml
.. note::
As to rnd_requirements.txt, usually, it is created when a dependent
library is not released. Once the dependency is installed
(will be released), the future
version of the dependency in the requirements.txt will be valid.
How to test your contribution
Although nose and doctest are both used in code testing, it is advisable
that unit tests are put in tests. doctest is incorporated only to make sure
the code examples in documentation remain valid across different development
releases.
On Linux/Unix systems, please launch your tests like this::
$ make
On Windows, please issue this command::
> test.bat
Before you commit
Please run::
$ make format
so as to beautify your code otherwise your build may fail your unit test.
.. testcode:: :hide:
import os os.unlink("your_file.xlsx") os.unlink("another_file.xlsx")
