write formatted values to csv not underlaying floats

[mszbot]

Firstly, this is a great library!

Image below shows the xlsx to the right and the csv output to the left.

Is it possible to write the formatted values from xlsx to csv? All as strings maybe?

At the moment, this library extracts the underlying float values from the cells and writes it to csv

Zamzar for example outputs formatted values as strings when using their xlsx to csv parser.
