I have extensive knowledge and experience in Excel data cleaning, analysis and presentation thanks to my experience working ofr an audit firm. During my two year as an auditor, I analysed heavy datasets, pertaining to all sorts of indicators (HR, energy, financial etc.), identified the errors/flaws in the available data through tests and screening, formalized all documents to enable usability for fellow workers, and analysed data by identifying main characteristics and categories as well as data trends through the use of Excel tools.
