**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 <https: github.com="" pyexcel="" pyexcel="">`__.

Known constraints
==================

Fonts, colors and charts are not supported.

Installation
================================================================================


You can install pyexcel-xlsxw via pip:

.. code-block:: bash

$ pip install pyexcel-xlsxw


or clone it and install it:

.. code-block:: bash

$ git clone https://github.com/pyexcel/pyexcel-xlsxw.git
$ cd pyexcel-xlsxw
$ python setup.py install

Support the project
================================================================================

If your company has embedded pyexcel and its components into a revenue generating
product, please `support me on patreon <https: www.patreon.com="" bepatron?u="5537627">`_ to
maintain the project and develop it further.

If you are an individual, you are welcome to support me too on patreon and for however long
you feel like. As a patreon, you will receive
`early access to pyexcel related contents <https: www.patreon.com="" pyexcel="" posts="">`_.

With your financial support, I will be able to invest
a little bit more time in coding, documentation and writing interesting posts.


Usage
================================================================================

As a standalone library
--------------------------------------------------------------------------------

Write to an xlsx file
********************************************************************************



Here's the sample code to write a dictionary to an xlsx file:

.. code-block:: python

>>> 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.

.. 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_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 = StringIO()
>>> 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")


Writing to a StringIO instance
********************************************************************************

You need to pass a StringIO instance to Writer:

.. code-block:: python

>>> data = [
... [1, 2, 3],
... [4, 5, 6]
... ]
>>> io = StringIO()
>>> 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

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

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.rst.

.. note::

As to rnd_requirements.txt, usually, it is created when a dependent
library is not released. Once the dependecy 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 adviable 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 systems, please issue this command::

> test.bat

How to update test environment and update documentation
---------------------------------------------------------

Additional steps are required:

#. pip install moban
#. git clone https://github.com/moremoban/setupmobans.git # generic setup
#. git clone https://github.com/pyexcel/pyexcel-commons.git commons
#. make your changes in `.moban.d` directory, then issue command `moban`

What is pyexcel-commons
---------------------------------

Many information that are shared across pyexcel projects, such as: this developer guide, license info, etc. are stored in `pyexcel-commons` project.

What is .moban.d
---------------------------------

`.moban.d` stores the specific meta data for the library.

Acceptance criteria
-------------------

#. Has Test cases written
#. Has all code lines tested
#. Passes all Travis CI builds
#. Has fair amount of documentation if your change is complex
#. Please update CHANGELOG.rst
#. Please add yourself to CONTRIBUTORS.rst
#. Agree on NEW BSD License for your contribution
