Working on spreadsheet software library

As a natural and logical extension from my Open XML spreadsheet guide, I’m writing a software library to create and manipulate Open XML spreadsheets.

What are these built-in styles? Check these out: For instance, Sebastien was asking how to use the “Good” and “Bad” built-in styles. […]
