A small task of reading an excel where yaml is already supported

You have to convert yaml file into csv(excel) in a same format as yaml. Means yaml is giving a dictionary which is readable in one of my project and i want to read the excel with the same classes, so u have to have same dictionary when excel will be read.

Yaml example:
general:
cost_file_version: 0
match_areas_and_grid_features: data.xls
export_file_name: abc
visualization:
consumption_min: 0
cheaper_than:
- file_name: base_supply.xlsx

dictionary generated:
{'general': {'cost_file_version': 0, 'match_areas': 'data.xls', 'file_name': 'abc', 'visualization': {'consumption_min': 0, 'cheaper_than': [{'file_name': 'base_supply.xlsx'}]}
