**pyexcel-xlsx** is a tiny wrapper library to read, manipulate and write data in xlsx and xlsm format using  `read_only` mode reader, `write_only` mode writer from openpyxl. You are likely to use it with `pyexcel <https://github.com/pyexcel/pyexcel>`__.

Please note:

1. `auto_detect_int` flag will not take effect because openpyxl detect integer in python 3 by default.
2. `skip_hidden_row_and_column` will get a penalty where `read_only` mode cannot be used.



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

Fonts, colors and charts are not supported.

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


You can install pyexcel-xlsx via pip:

.. code-block:: bash

    $ pip install pyexcel-xlsx


or clone it and install it:

.. code-block:: bash

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

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_xlsx 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)


Read from an xlsx file
********************************************************************************

Here's the sample code:

.. code-block:: python

    >>> from pyexcel_xlsx 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_xlsx 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




Read from an xlsx from memory
********************************************************************************

Continue from previous example:

.. 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)
    >>> print(json.dumps(data))
    {"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [[7, 8, 9], [10, 11, 12]]}


Pagination feature
********************************************************************************



Let's assume the following file is a huge xlsx file:

.. code-block:: python

   >>> huge_data = [
   ...     [1, 21, 31],
   ...     [2, 22, 32],
   ...     [3, 23, 33],
   ...     [4, 24, 34],
   ...     [5, 25, 35],
   ...     [6, 26, 36]
   ... ]
   >>> sheetx = {
   ...     "huge": huge_data
   ... }
   >>> save_data("huge_file.xlsx", sheetx)

And let's pretend to read partial data:

.. code-block:: python

   >>> partial_data = get_data("huge_file.xlsx", start_row=2, row_limit=3)
   >>> print(json.dumps(partial_data))
   {"huge": [[3, 23, 33], [4, 24, 34], [5, 25, 35]]}

And you could as well do the same for columns:

.. code-block:: python

   >>> partial_data = get_data("huge_file.xlsx", start_column=1, column_limit=2)
   >>> print(json.dumps(partial_data))
   {"huge": [[21, 31], [22, 32], [23, 33], [24, 34], [25, 35], [26, 36]]}

Obvious, you could do both at the same time:

.. code-block:: python

   >>> partial_data = get_data("huge_file.xlsx",
   ...     start_row=2, row_limit=3,
   ...     start_column=1, column_limit=2)
   >>> print(json.dumps(partial_data))
   {"huge": [[23, 33], [24, 34], [25, 35]]}

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.


Reading from an xlsx file
********************************************************************************

Here is the sample code:

.. 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")


Reading from a IO instance
********************************************************************************

You got to wrap the binary content with stream to get xlsx working:

.. 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']
    >>> xlsxfile = "another_file.xlsx"
    >>> with open(xlsxfile, "rb") as f:
    ...     content = f.read()
    ...     r = pe.get_book(file_type="xlsx", file_content=content)
    ...     print(r)
    ...
    Sheet 1:
    +---+---+---+
    | 1 | 2 | 3 |
    +---+---+---+
    | 4 | 5 | 6 |
    +---+---+---+
    Sheet 2:
    +-------+-------+-------+
    | row 1 | row 2 | row 3 |
    +-------+-------+-------+


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-xlsx.git
#. cd pyexcel-xlsx

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
#. run 'make format' so as to confirm the pyexcel organisation's coding style
#. Please update CHANGELOG.rst
#. Please add yourself to CONTRIBUTORS.rst
#. Agree on NEW BSD License for your contribution
