File readers is a library that currently includes reader for Excel and CSV files. By default the library includes a data collector for each reader. The default data collectors might be sufficient for most basic cases. The library has been design to be extendable. Users can inherit the base data collector and write their own implementation, which can then be injected into one of the reader classes. More documentation about the libary will be added soon.
The default Excel reader is the simplest class to start with. The only requirement for using the default Excel reader is to have the header row on the first row in the Excel file, since it creates a dictionary of each row for easy row searching.
Currently the best way to find out how to use the reader and data collector classes is by looking at the tests.
