Introduction
================================================================================

Feature Highlights
===================

1. One application programming interface(API) to handle multiple data sources:

   * physical file
   * memory file
   * SQLAlchemy table
   * Django Model
   * Python data structures: dictionary, records and array
2. One API to read and write data in various excel file formats.
3. For large data sets, data streaming are supported. A genenerator can be returned to you. Checkout iget_records, iget_array, isave_as and isave_book_as. 




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

You can install pyexcel via pip:

.. code-block:: bash

    $ pip install pyexcel


or clone it and install it:

.. code-block:: bash

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



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

Please note that you will have to use '.sortable.html' in order to replicate the example.

.. image:: https://github.com/pyexcel/pyexcel-sortable/raw/master/sortable.gif

.. code-block:: python

    >>> # pip install pyexcel-text==0.2.7.1
    >>> import pyexcel as p
    >>> ccs_insight2 = p.Sheet()
    >>> ccs_insight2.name = "Worldwide Mobile Phone Shipments (Billions), 2017-2021"
    >>> ccs_insight2.ndjson = """
    ... {"year": ["2017", "2018", "2019", "2020", "2021"]}
    ... {"smart phones": [1.53, 1.64, 1.74, 1.82, 1.90]}
    ... {"feature phones": [0.46, 0.38, 0.30, 0.23, 0.17]}
    ... """.strip()
    >>> ccs_insight2
    pyexcel sheet:
    +----------------+------+------+------+------+------+
    | year           | 2017 | 2018 | 2019 | 2020 | 2021 |
    +----------------+------+------+------+------+------+
    | smart phones   | 1.53 | 1.64 | 1.74 | 1.82 | 1.9  |
    +----------------+------+------+------+------+------+
    | feature phones | 0.46 | 0.38 | 0.3  | 0.23 | 0.17 |
    +----------------+------+------+------+------+------+



Suppose you have the following data in a dictionary:

========= ====
Name      Age
========= ====
Adam      28
Beatrice  29
Ceri      30
Dean      26
========= ====

you can easily save it into an excel file using the following code:

.. code-block:: python

   >>> import pyexcel
   >>> # make sure you had pyexcel-xls installed
   >>> a_list_of_dictionaries = [
   ...     {
   ...         "Name": 'Adam',
   ...         "Age": 28
   ...     },
   ...     {
   ...         "Name": 'Beatrice',
   ...         "Age": 29
   ...     },
   ...     {
   ...         "Name": 'Ceri',
   ...         "Age": 30
   ...     },
   ...     {
   ...         "Name": 'Dean',
   ...         "Age": 26
   ...     }
   ... ]
   >>> pyexcel.save_as(records=a_list_of_dictionaries, dest_file_name="your_file.xls")


And here's how to obtain the records:

.. code-block:: python

   >>> import pyexcel as p
   >>> records = p.iget_records(file_name="your_file.xls")
   >>> for record in records:
   ...     print("%s is aged at %d" % (record['Name'], record['Age']))
   Adam is aged at 28
   Beatrice is aged at 29
   Ceri is aged at 30
   Dean is aged at 26
   >>> p.free_resources()


Advanced usage :fire:
----------------------

If you are dealing with big data, please consider these usages:

   >>> def increase_everyones_age(generator):
   ...     for row in generator:
   ...         row['Age'] += 1
   ...         yield row
   >>> def duplicate_each_record(generator):
   ...     for row in generator:
   ...         yield row
   ...         yield row
   >>> records = p.iget_records(file_name="your_file.xls")
   >>> io=p.isave_as(records=duplicate_each_record(increase_everyones_age(records)),
   ...     dest_file_type='csv', dest_lineterminator='\n')
   >>> print(io.getvalue())
   Age,Name
   29,Adam
   29,Adam
   30,Beatrice
   30,Beatrice
   31,Ceri
   31,Ceri
   27,Dean
   27,Dean
   <BLANKLINE>

Two advantages of above method:

#. Add as many wrapping functions as you want.
#. Constant memory consumption

In order to manage the list of plugins installed, you need to use pip to add or remove
a plugin. When you use virtualenv, you can have different plugins per virtual
environment. In the situation where you have multiple plugins that does the same thing
in your environment, you need to tell pyexcel which plugin to use per function call.
For example, pyexcel-ods and pyexcel-odsr, and you want to get_array to use pyexcel-odsr.
You need to append get_array(..., library='pyexcel-odsr').

#. remove get_{{file_type}}_stream functions from pyexcel.Sheet and pyexcel.Book
   introduced since 0.4.3.

0.4.3 - 26.01.2017
--------------------------------------------------------------------------------

Added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. '.stream' attribute are attached to `~pyexcel.Sheet` and `~pyexcel.Book` to
   get direct access the underneath stream in responding to file type
   attributes, such as sheet.xls. it helps provide a custom stream to external
   world, for example, Sheet.stream.csv gives a text stream that contains csv
   formatted data. Book.stream.xls returns a xls format data in a byte stream.

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. Better error reporting when an unknown parameters or unsupported file types
   were given to the signature functions.

0.4.2 - 17.01.2017
--------------------------------------------------------------------------------

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. Raise exception if the incoming sheet does not have column names. In other
   words, only sheet with column names could be saved to database. sheet with
   row names cannot be saved. The alternative is to transpose the sheet, then
   name_columns_by_row and then save.
#. fix iget_records where a non-uniform content should be given, e.g. [["x",
   "y"], [1, 2], [3]], some record would become non-uniform, e.g. key 'y' would
   be missing from the second record.
#. `skip_empty_rows` is applicable when saving a python data structure to
   another data source. For example, if your array contains a row which is
   consisted of empty string, such as ['', '', '' ... ''], please specify
   `skip_empty_rows=False` in order to preserve it. This becomes subtle when you
   try save a python dictionary where empty rows is not easy to be spotted.
#. `#69 <https://github.com/pyexcel/pyexcel/issues/69>`_: better documentation
   for save_book_as.

0.4.1 - 23.12.2016
--------------------------------------------------------------------------------

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. `#68 <https://github.com/pyexcel/pyexcel/issues/68>`_: regression
   save_to_memory() should have returned a stream instance.

0.4.0 - 22.12.2016
--------------------------------------------------------------------------------

Added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. `Flask-Excel#19 <https://github.com/pyexcel/Flask-Excel/issues/19>`_ allow
   sheet_name parameter
#. `pyexcel-xls#11 <https://github.com/pyexcel/pyexcel-xls/issues/11>`_
   case-insensitive for file_type. `xls` and `XLS` are treated in the same way

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. `#66 <https://github.com/pyexcel/pyexcel/issues/66>`_: `export_columns` is
   ignored
#. Update dependency on pyexcel-io v0.3.0

0.3.3 - 07.11.2016
--------------------------------------------------------------------------------

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

--------------------------------------------------------------------------------

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. `#62 <https://github.com/pyexcel/pyexcel/issues/62>`_: optional module import
   error become visible.

0.3.0 - 28.10.2016
--------------------------------------------------------------------------------

Added:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. file type setters for Sheet and Book, and its documentation
#. `iget_records` returns a generator for a list of records and should have
   better memory performance, especially dealing with large csv files.
#. `iget_array` returns a generator for a list of two dimensional array and
   should have better memory performance, especially dealing with large csv
   files.
#. Enable pagination support, and custom row renderer via pyexcel-io v0.2.3

Updated
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

#. Take `isave_as` out from `save_as`. Hence two functions are there for save a
   sheet as
#. `#60 <https://github.com/pyexcel/pyexcel/issues/60>`_: encode 'utf-8' if the
   console is of ascii encoding.
#. `#59 <https://github.com/pyexcel/pyexcel/issues/59>`_: custom row renderer
#. `#56 <https://github.com/pyexcel/pyexcel/issues/56>`_: set cell value does
   not work
#. pyexcel.transpose becomes `pyexcel.sheets.transpose`
#. iterator functions of `pyexcel.Sheet` were converted to generator functions

   * `pyexcel.Sheet.enumerate()`

   * `pyexcel.Sheet.named_rows()`
   * `pyexcel.Sheet.named_columns()`

#. `~pyexcel.Sheet.save_to_memory` and `~pyexcel.Book.save_to_memory` return the
   actual content. No longer they will return a io object hence you cannot call
   getvalue() on them.
