Pyspread is a non-traditional spreadsheet application that is based on and
written in the programming language Python.

The goal of pyspread is to be the most pythonic spreadsheet.
Pyspread expects Python expressions in its grid cells, which makes a
spreadsheet specific language obsolete. Each cell returns a Python object
that can be accessed from other cells. These objects can represent anything
including lists or matrices.

Pyspread is free software. It is released under the GPL v3.

- CSV import and export
- Chart creation dialog based on matplotlib
- Python objects as cell results
- Python macros
- GPG based save file signatures for preventing foreign code execution
- Access to all Python modules from within cells. These modules allow
  for example matrix operations via numpy or fixed point decimal
  numbers for business calculations via decimal.

Optional Requirements: python-xlrd (optional for opening Excel files)
