{data.io} main functions are read() and write(). They are made super-easy to import and export data in various formats in an unified way (they use functions from other packages under the hood like {haven}, {readr}, {readxl}, {writexl}, …). They care about metadata, in particular, meaningful labels and units for the variables. Also, a mechanism to preprocess data sets using sidecar files, and to translate them into various languages are provided for a subset of R packages data sets.
