Excel expert for reporting and statistics

Reporting and statistics are related for past and future purchases for a company. The data is provided and exported by me from different software, for example SAP export and/or accounting software data exports. The excel expert needs to gather all data and centralize them in a structured way in excel, with pivot tables, filtering options etc.
At the end, it is a job of creativity combined with a centralization of different information in an all-in-one excel file.
