1. If the data file is in the form of a rectangular table with rows and
columns and the first row is a header row then if, in Excel, it is saved as
a .csv file it can be read into R like this:

   DF <- read.csv("/Users/JoeDoe/myspreadsheet.csv")

2. The openxlsx, readxl (and a number of other packages) can alternetely be
used to directly read in an xls or xlsx file, e.g.

  install.packages("readxl")
  library(readxl)
  DF <- read_excel("/Users/JoeDoe/myspreadsheet.xlsx")

3. The Windows magnifier that comes with Windows does work with R.
