Working in a spreadsheet can get messy and confusing. Especially if you have a very large dataset and need to perform many operations. You have to document each step to be able to repeat the same analyses later on. Fortunately there is R.
With a few simple lines of code you can do the same things in R as in a spreadsheet: cleaning, sorting, filtering, grouping (pivot tables), statistics and charts, but now in a clear workflow that can easily be changed, repeated (for example with a new dataset) and shared. Experience why R (freeware) in a short time has conquered the hearts of many data journalists.
