Read All Excel Files into R by Sheet with file name as column

Question

I have a local folder with excel files in the same format. Each excel file has 10 sheets.

I want to be able to do the following:

1) Read all the excel files in R

2) Rbind all the results together but by sheet .

3) Result would be 10 new dataframes with all the excel files rbinded together.

4) New column will be added with file name

I have looked up code and the best I could find is this but it doesn't do it by sheet:

files = list.files()
library(plyr)
library(readr)
library(readxl)
data2=lapply(files, read_excel)
for (i in 1:length(data2)){data2[[i]]<-cbind(data2[[i]],files[i])}
all_data <- do.call("rbind.fill", data2) 

Has anyone had any success with this?

Thanks in advance

If you'd like you can also vectorize it using the tidyverse approach.

require(tidyverse)

df <- list.files(path = "your_path",
                       full.names = TRUE,
                       recursive = TRUE,
                       pattern = "*.xls") %>% 
tbl_df() %>%
mutate(sheetName = map(value, readxl::excel_sheets)) %>%
unnest(sheetName) %>% 
mutate(myFiles = purrr::map2(value, sheetName, function(x,y) {
    readxl::read_excel(x, sheet = paste(y))})) %>% 
unnest(myFiles)
