Dynamically converting a list of Excel files to csv files in R

r csv xlsx

I currently have a folder containing all Excel (.xlsx) files, and using R I would like to automatically convert all of these files to CSV files using the "openxlsx" package (or some variation). I currently have the following code to convert one of the files and place it in the same folder:convert("team_order\\team_1.xlsx", "team_order\\team_1.csv")

I would like to automate the process so it does it to all the files in the folder, and also removes the current xlsx files, so only the csv files remain. Thanks!

You can try this using rio, since it seems like that's what you're already using:

library("rio")
xls <- dir(pattern = "xlsx")
created <- mapply(convert, xls, gsub("xlsx", "csv", xls))
unlink(xls) # delete xlsx files
