cut,copy,paste excel for finance

I am looking to upskill quickly in data management and data science. I use excel regularly but end up outsouring when i need things done quickly or when tasks are more advanced --building financial analysis tools (DCFs, regression analysis etc), charts or need to automate (macros). I need someone who really understands finance especially time series analysis. In addition I will be looking to pickup python after this so the data science (statistics) knowledge should be transferable Get earning from cut,copy,paste... Data entry job.. just copy and paste the content!
