I have used and trained Microsoft Excel in an Accounting environment for 15 years. In that time I have learned how to use many of the Excel functions in order to help me manipulate my financial data better. I work on many spreadsheets in my office and have helped many accountants to work more efficient by teaching them tricks and tips in Excel.
I have also worked a lot with pivot tables and interactive dashboards to display financial information. All of these skills have helped me to master so many aspects of Excel to enable me to work more efficiently and also to train other accountants in using Excel.
In addition to training people in my office, I also do freelance Excel work for other companies when they need an excel expert. Additionally I write tutorials and make videos and post on a blog to help train more people in using Excel.
