For directly reading Excel sheets I highly recommend "readxl" from the
R package bundle "tidyverse".

It's an investment though but it pays in the long run for serious data
science.  After processing you should be able to write data in an excel
file with the "writexl" package.  (Did not test it, never had the need
to export into Excel. :-))

By the way, I'm mostly doing data processing in org-mode R source
blocks.  And I'm also converting data into org-mode tables but mostly
small ones for latex table exports. And you can also do spreadsheet
calculations with them

      https://orgmode.org/manual/The-Spreadsheet.html

Here's a small example

       #+LATEX: \definecolor{VitescoYellow}{RGB}{242,229,0}
       #+LATEX: \rowcolors[]{1}{VitescoYellow!100}{VitescoYellow!5}
       #+caption: Required motor torque to reach src_R{N} rpm in src_R{T} s
       | *Cases*    | *Torque* in  Nmm |
       |------------+------------------|
       | Best case  |              9.5 |
       | Worst case |             11.6 |
       #+TBLFM: @2$2='(org-sbe mintorque):: @3$2='(org-sbe maxtorque)

(Above org table is reading results from named org source blocks.)

If you really, really need to return data in MS formats you might have
to run a virtual machine with Windows, not that I recommend that but
live is ...

Hope that is interesting
