Is there an R function to export /convert excel file into text file?

I am trying to find a code for converting an excel file into text file.

This is the code for Excel workbook. I want to convert it into text file.

template <- loadWorkbook('V:/rcode/template.xlsx')

writeData(template,'sheet1',finaloutput, startRow =1,startCol = 3, colNames = FALSE)

workbook<- paste0("V:/rcode/", 'template', ".xlsx")

saveWorkbook(template, workbook, overwrite = TRUE)
