Excel sheet

I need help creating an Excel sheet that can compile data, utilize formulas, and export the compiled data. I understand the complexity of this type of project, so I want to ensure that the person I hire is experienced in working with Excel. They will need to be knowledgeable of data visualizations, as well as being able to create graphs with the data. The sheet needs to be able to export the compiled data, so I need someone comfortable with this aspect of the project. It is important that the person I hire be able to deliver a product that functions correctly and is of the highest quality.
