As an accomplished professional with extensive experience as both, a Data Scientist and Programmer, I firmly believe I'm the perfect fit for your Excel-based project. My strong expertise in a wide range of tools and languages, primarily including Excel (VBA Macro, Advance Formula and more), Python (using libraries like Pandas, NumPy, Matplotlib, Seaborn) and R, make it easier for me to efficiently handle data processing tasks with complex requirements.
My experience as a mathematician aids me in maintaining a strong attention to detail while comparing the numeric discrepancies in your multiple Excel files. In addition, my analytical background empowers me to not just highlight these differences for you but assess their implications too; ensuring you have a clear picture of the data disparities. I am confident that my skills will guarantee accurate analysis while retaining the original format and order of your files/sheets.
To further substantiate my abilities, I have also deployed machine learning and statistical models on large datasets which improving my ability to recognize hidden trends. These skills will go hand in hand with this project which demands a solid understanding of numerical comparision in Excel. I am eagerly looking forward to leveraging my expertise to deliver results that exceed your expectations!
