I want to read an excel file, insert some data, add some data validation functions to the sheet and save the Excel file. I had a look at both  and .  can read files but can’t edit.  can edit but can’t read an existing file. I tried using both to achieve what I want but still  can only read the cell values but don’t read the existing formulas. Is there any library that I can use to make this work in Elixir?
Or should I start looking at python to get this done?
Any help will be very appreciated
