How to extract sheet names from Excel file in R

Question

I have loaded a workbook into R and read in the worksheets using xlConnect, but I was wondering if there was a way of extracting the names of the sheets perhaps in a vector?

So far my code is:

dataIn<-loadWorkbook(file.path(filenames[1],sep=""))
lst = readWorksheet(dataIn, sheet = getSheets(dataIn), startRow=1, startCol=1, header=TRUE)

...and I want to extract the sheet names of the sheets in lst.

Answer 1

Another really nice package developed by the folks at RStudio is readxl. It's easy to get the excel sheet names with the excel_sheets() function.

library(readxl)
path <- "path/to/your/file.xlsx"
excel_sheets(path = path)

Answer 2

You are looking for getSheets

Returns all worksheet names in a workbook.

Answer 3

In the "openxlsx" package it would be a command "getSheetNames":

library(openxlsx)
path <- "path/to/your/file.xlsx"
getSheetNames(path)

Answer 4

Here is another approach that can be considered :

library(RDCOMClient)
xlApp <- COMCreate("Excel.Application")
xlApp[["DisplayAlerts"]] <- FALSE
xlApp[["Visible"]] <- TRUE

path_To_Excel_File <- "D:/excel_File.xlsx"
xlWbk <- xlApp$Workbooks()$Open(path_To_Excel_File)
nb_Sheets <- xlWbk$Sheets()$Count()
sheets_Names <- character(nb_Sheets)

for(i in 1 : nb_Sheets)
{
  sheets_Names[i] <- xlWbk$Sheets(i)$Name()
}
