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

And your issues will get prioritized if you would like to become my patreon as pyexcel pro user.

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

Known constraints

Fonts, colors and charts are not supported.

Nor to read password protected xls, xlsx and ods files.

Introduction

pyexcel-io provides one application programming interface(API) to read and write the data in excel format, import the data into and export the data from database. It provides support for csv(z) format, django database and sqlalchemy supported databases. Its supported file formats are extended to cover "xls", "xlsx", "ods" by the following extensions:

.. _file-format-list: .. _a-map-of-plugins-and-file-formats:

.. table:: A list of file formats supported by external plugins

Plugin shopping guide

Since 2020, all pyexcel-io plugins have dropped the support for python versions which are lower than 3.6. If you want to use any of those Python versions, please use pyexcel-io and its plugins versions that are lower than 0.6.0.

Except csv files, xls, xlsx and ods files are a zip of a folder containing a lot of xml files

The dedicated readers for excel files can stream read

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').

If you need to manipulate the data, you might do it yourself or use its brother library pyexcel <https://github.com/pyexcel/pyexcel>__ .

If you would like to extend it, you may use it to write your own extension to handle a specific file format.

Installation

You can install pyexcel-io via pip:

.. code-block:: bash

$ pip install pyexcel-io

or clone it and install it:

.. code-block:: bash

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

Development guide

Development steps for code changes

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

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.yml

.. 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, 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.
