dstream_excel.dstream.workbook.create.create_all_xlsx_with_datastream_command(folder, symbol_list, variables, **dstream_kwargs)[source]¶

Creates XLSX files containing Datastream functions

The XLSX files will not be populated with data at this point, only the function itself. The files must then be populated, then combined.

Parameters

folder (str) – Folder in which to create Excel files
symbol_list (Sequence[str]) – Datastream symbols representing companies. Available by selecting a list through filters in Eikon, then getting an output of that list.
variables (Sequence[str]) – Time-series variables to download
dstream_kwargs – can pass begin, end, or freq. All of these arguments take day, month, and year as D, M, and Y. freq can be set to D, M, or Y. begin and end can be set to just Y but combined with a time modifier, e.g. begin=’-5Y’. Don’t pass end to have the data go up to current.
