Introduction¶
pyexcel provides one application programming interface to read, manipulate and write data in different excel formats. This library makes information processing involving excel files an enjoyable task. The data in excel files can be turned into array or dict with least code, vice versa. This library focuses on data processing using excel files as storage media hence fonts, colors and charts were not and will not be considered.
The idea originated from the common usability problem when developing an excel file driven web applications for non-technical office workers: such as office assistant, human resource administrator. The fact is that not all people know the difference among various excel formats: csv, xls, xlsx. Instead of training those people about file formats, this library helps web developers to handle most of the excel file formats by providing a common programming interface. To add a specific excel file format to you application, all you need is to install an extra pyexcel plugin. No code change to your application. Looking at the community, this library and its associated ones try to become a small and easy to install alternative to Pandas.
Installation¶
You can install it via pip:
$ pip install pyexcel
or clone it and install it:
$ git clone https://github.com/pyexcel/pyexcel.git

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’).

Here are the example usages:

>>> for record in records:
... print("%s is aged at %d" % (record['Name'], record['Age']))

Beatrice is aged at 29
Ceri is aged at 30
Dean is aged at 26
>>> pe.free_resources()
