pyexcel-xlsxw - Let you focus on data, instead of xlsx format

pyexcel-xlsxw is a tiny wrapper library to write data in xlsx and xlsm fromat using xlsxwriter. You are likely to use it with 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. 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-xlsxw via pip:

$ pip install pyexcel-xlsxw

or clone it and install it:

$ git clone https://github.com/pyexcel/pyexcel-xlsxw.git
$ cd pyexcel-xlsxw
$ 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:

>>> from pyexcel_xlsxw 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.

>>> 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:

>>> from pyexcel_xlsxw 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.

>>> # 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.

>>> 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:

>>> sheet.save_as("another_file.xlsx")

Writing to a BytesIO instance

You need to pass a BytesIO instance to Writer:

>>> data = [
...     [1, 2, 3],
...     [4, 5, 6]
... ]
>>> io = BytesIO()
>>> sheet = pe.Sheet(data)
>>> io = sheet.save_to_memory("xlsx", io)
>>> # then do something with io
>>> # In reality, you might give it to your http response
>>> # object for downloading

Developer guide

Development steps for code changes

1. git clone https://github.com/pyexcel/pyexcel-xlsxw.git
2. cd pyexcel-xlsxw

Upgrade your setup tools and pip. They are needed for development and testing only:

1. pip install --upgrade setuptools pip

Then install relevant development requirements:

1. pip install -r rnd_requirements.txt # if such a file exists
2. pip install -r requirements.txt
3. 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")
