openxlsx2

This R package is a modern reinterpretation of the widely used popular openxlsx package. Similar to its predecessor, it simplifies the creation of xlsx files by providing a clean interface for writing, designing and editing worksheets. Based on a powerful XML library and focusing on modern programming flows in pipes or chains, openxlsx2 allows to break many new ground.

Installation

You can install the stable version of openxlsx2 with:

install.packages('openxlsx2')

You can install the development version of openxlsx2 from GitHub with:

# install.packages("remotes")
remotes::install_github("JanMarvin/openxlsx2")

Or from r-universe with:

# Enable repository from janmarvin
options(repos = c(
  janmarvin = 'https://janmarvin.r-universe.dev',
  CRAN = 'https://cloud.r-project.org'))
# Download and install openxlsx2 in R
install.packages('openxlsx2')

Introduction

openxlsx2 aims to be the swiss knife for working with the openxml spreadsheet formats xlsx, xlsm and (limited) xlsb (other formats of other spreadsheet software are not supported). We offer two different variants how to work with openxlsx2.

  • The first one is to simply work with R objects. It is possible to read (read_xlsx()) and write (write_xlsx()) data from and to files. We offer a number of options in the commands to support various features of the openxml format, including reading and writing named ranges and tables. Furthermore, there are several ways to read certain information of an openxml spreadsheet without having opened it in a spreadsheet software before, e.g. to get the contained sheet names or tables.
  • As a second variant openxlsx2 offers the work with so called wbWorkbook objects. Here an openxml file is read into a corresponding wbWorkbook object (wb_load()) or a new one is created (wb_workbook()). Afterwards the object can be further modified using various functions. For example, worksheets can be added or removed, the layout of cells or entire worksheets can be changed, and cells can be modified (overwritten or rewritten). Afterwards the wbWorkbook objects can be written as openxml files and processed by suitable spreadsheet software.

Many examples how to work with openxlsx2 are in our manual pages and in our vignettes. You can find them under:

vignette(package = "openxlsx2")

Example

This is a basic example which shows you how to solve a common problem:

library(openxlsx2)
# read xlsx or xlsm files
path <- system.file("extdata/openxlsx2_example.xlsx", package = "openxlsx2")
read_xlsx(path)
#>     Var1 Var2 NA  Var3  Var4       Var5         Var6    Var7     Var8
