 ## to_excel.py
 to_excel.py provides the ToExcel class, which is a way to export an existing layer file as an Excel 
 spreadsheet. The ToExcel class has an optional parameter for the initialization function, that 
-tells the exporter what data source to use when building the output matrix. Valid options include using live data from cti-taxii.mitre.org, using data from the Mitre cti repository, or using a local collection.

 ##### ToExcel()
 ```python
 x = ToExcel(domain='enterprise', source='taxii', local=None)
 ```
 The ToExcel constructor takes domain, server, and local arguments during instantiation. The domain can 
-be either `enterprise` or `mobile`, and can be pulled directly from a layer file as `layer.domain`. The source argument tells the matrix generation tool which data source to use when building the matrix. `taxii` indicates that the tool should utilize the `cti-taxii` server when building the matrix, while the `repo` and `local` options indicate that it should use the repository and a local collection respectively. The local argument is only required if the source is set to `local`, in which case it should be a path to a local stix collection.
