Installation

Recently, pyexcel(0.2.2+) and its plugins(0.2.0+) started using newer version of setuptools. Please upgrade your setup tools before install latest pyexcel components:

$ pip install --upgrade setuptools

You can install it via pip:

$ pip install pyexcel

or clone it and install it:

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

Installation of individual plugins , please refer to individual plugin page.

Usage

JSON

>>> import pyexcel as pe
>>> an_array = [[1,2]]
>>> sheet = pe.Sheet(an_array)
>>> sheet.json
'{"pyexcel sheet": [[1, 2]]}'

Note: It is available with pyexcel v0.2.1 and pyexcel-text 0.2.0

TSV

>>> sheet.tsv
'1\t2\r\n'

Note: TSV and the rest of the formats are available with pyexcel v0.2.2 and its plugins at version 0.2.0+ only

CSV

>>> sheet.csv

Development guide

Development steps for code changes

  1. git clone https://github.com/pyexcel/pyexcel.git
  2. cd pyexcel
  3. pip install -r rnd_requirements.txt # if such a file exists
  4. pip install -r requirements.txt
  5. pip install -r tests/requirements.txt

In order to update test envrionment, and documentation, additional setps are required:

  1. pip install moban
  2. git clone https://github.com/pyexcel/pyexcel-commons.git
  3. make your changes in .moban.d directory, then issue command moban

What is rnd_requirements.txt

Usually, it is created when a depdent 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.

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.

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 test

On Windows systems, please issue this command:

> test.bat
