Portable, light-weight data frame to xlsx exporter based on libxlsxwriter. No Java or Excel required.
Wraps the libxlsxwriter library to create files in Microsoft Excel 'xlsx' format.
install.packages("writexl")Currently the package only has write_xlsx() to export a data frame to xlsx.
library(writexl)
library(readxl)
tmp <- writexl::write_xlsx(iris)
readxl::read_xlsx(tmp)# A tibble: 150 x 5

Most data types should roundtrip with readxl:
library(nycflights13)
out <- readxl::read_xlsx(writexl::write_xlsx(flights))
all.equal(out, flights)
## TRUEPerformance is a bit better than openxlsx implementation:
library(microbenchmark)
library(nycflights13)
microbenchmark(
writexl = writexl::write_xlsx(flights, tempfile()),
openxlsx = openxlsx::write.xlsx(flights, tempfile()),
times = 5
)

writexl::write_xlsx(flights, tmp1 <- tempfile())
file.info(tmp1)$size
## 29157282openxlsx::write.xlsx(flights, tmp2 <- tempfile())
file.info(tmp2)$size
