        **pyexcel-xlsxr** is a specialized xlsx reader using lxml. It does partial reading, meaning
        it wont load all content into memory.
        
        
        lxml installation
        =================
        
        This library depends on lxml. Because its availablity, the use of this library is restricted.
        
        for PyPy, lxml == 3.4.4 are tested to work well. But lxml above 3.4.4 is difficult to get installed.
        
        for Python 3.7, please use lxml==4.1.1.
        
        Otherwise, this library works OK with lxml 3.4.4 or above.

            $ cd pyexcel-xlsxr
            $ python setup.py install
        
        Usage
        ================================================================================
        
        As a standalone library
        --------------------------------------------------------------------------------
        
        Read from an xlsx file
        ********************************************************************************
        
        Here's the sample code:
        
        .. code-block:: python
        
            >>> from pyexcel_xlsxr 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"]]}
        
        
        
        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 |
            +-------+-------+-------+
        
        
        
        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 |
            +-------+-------+-------+

        Developer guide
        ==================
        
        Development steps for code changes
        
        #. git clone https://github.com/pyexcel/pyexcel-xlsxr.git
        #. cd pyexcel-xlsxr
        
        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
        
        
        Before you commit
        ------------------------------
        
        Please run::
        
            $ make format
        
        so as to beautify your code otherwise travis-ci may fail your unit test.
        
        
        And make sure you would have run moban command
        ---------------------------------------------------------
        
        Additional steps are required:
        
        #. pip install moban
        #. make your changes in `.moban.d` directory, then issue command `moban`
        #. moban
        
        otherwise travis-ci may also fail your unit test.
        
        What is .moban.d
        ---------------------------------
        
        `.moban.d` stores the specific meta data for the library.
