pyexcel-io - Let you focus on data, instead of file formats

Known constraints

Fonts, colors and charts are not supported.

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:

A list of file formats supported by external plugins
Package name Supported file formats Dependencies Python versions
pyexcel-io csv, csvz [1], tsv, tsvz [2]   2.6, 2.7, 3.3, 3.4, 3.5, 3.6 pypy
pyexcel-xls xls, xlsx(read only), xlsm(read only) xlrd, xlwt same as above
pyexcel-xlsx xlsx openpyxl same as above
pyexcel-xlsxw xlsx(write only) XlsxWriter same as above
pyexcel-ods3 ods ezodf, lxml 2.6, 2.7, 3.3, 3.4 3.5, 3.6
pyexcel-ods ods odfpy same as above


[1]zipped csv file
[2]zipped tsv file

If you need to manipulate the data, you might do it yourself or use its brother library pyexcel .

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


You can install it via pip:

$ pip install pyexcel-io

or clone it and install it:

$ git clone
$ cd pyexcel-io
$ python install

Development guide

Development steps for code changes

  1. git clone
  2. cd pyexcel-io

Upgrade your setup tools and pip. They are needed for development and testing only:

  1. pip install --upgrade setuptools "pip==7.1"

Then install relevant development requirements:

  1. pip install -r rnd_requirements.txt # if such a file exists
  2. pip install -r requirements.txt
  3. pip install -r tests/requirements.txt

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

  1. pip install moban
  2. git clone commons
  3. make your changes in .moban.d directory, then issue command moban

What is 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.

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
