A character vector containing the names of the files or directories in the specified directory is created by the list.files() function.

list.files(path = “.”, pattern = NULL, all.files = FALSE,full.names = FALSE, recursive = FALSE, ignore.case = FALSE, include.dirs = FALSE, no.. = FALSE)
A list of the same length as X is returned by the lapply() function, and each element of that list contains the results of applying FUN to the corresponding element of X.

The efficient implementation of the common pattern of do.call(rbind, dfs) or do.call(cbind, dfs) for joining many data frames into one is the bind rows() function.
Syntax:
bind_rows(…, .id = NULL)
library("dplyr")
library("plyr")
library("readr")
library("readxl")
data <- list.files(path = "Location/to/folder",
pattern = "*.xlsx",
full.names = TRUE) %>%
lapply(read_excel) %>%
bind_rows
