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. And ready-made custom filters and formatters can be applied. This library focuses on data processing using excel files as storage media hence fonts, colors and charts were not and will not be considered.

Excel files are de-facto file format for information sharing in non-software centric organisations. Excel files are not only used for mathematical computation in financial institutions but also used for many other purposes in an office work environment. This is largely casued by wide adoption of Microsoft Office. Comparing the existing, mathematics savvy Pandas library, this library intends to help data processing job where data extraction is more important than data analysis. In such context, ease of use, and low overhead is preferred, while Pandas is as big as 4MB and contains hundreds of potentially useful functions.

Name Age
Adam 28
Beatrice 29
Ceri 30
Dean 26

Here are the example usages:

>>> import pyexcel as pe
>>> import pyexcel.ext.xls # import it to handle xls file
>>> import pyexcel.ext.xlsx # import it to handle xlsx file
>>> records = pe.get_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
