# This sample code will get data from excel files that are sent as gmail attachments by scraping the embedded "sheet1.xml" files, if the files are formatted the same way.

# The data in each attachment (in this example, arrest records) will be saved a csv file in the "outpath" subdirectory. The csvs can later be combined using csvkit or another tool if so desired.

# Code originally written in Python 2.7 (sorry!)
