Removing Password from an Excel file and top 5 rows

Question

HI All,

I have a password encrypted file and the file also contains 5 rows of junk information which i need to remove before the 6th row should be the column headers.

I am using the R to remove the encryption. how ever my R code is failing and i am not sure why.  i was hoping the code would output everything with the junk rows decrypted and then i would clean up the top 5 rows and headers using dynamic rename.

here is the code i am using:

#install.packages(c("excel.link"),repos='https://cran.revolutionanalytics.com/',dependencies = TRUE)
library("excel.link")

df <- read.Alteryx("#1", mode="data.frame")
filename <- as.character(df[1,"FullPath"])
excel_pwd <- as.character(df[1,"excel_password"])

excel_data <- xl.read.file(filename, password = excel_pwd, write.res.password=excel_pwd)

output <- lapply(excel_data, as.character)

output <- as.data.frame(output)

write.Alteryx(output, 1)

not sure what i am missing or needs to be done to get the correct output

The file screenshot is attached. as you can see the top 5 rows r just random information that needs to be removed and then row 6 is the actual headers of the file once encrypted

Not OP or the helper, but the issue is the code is different:

This will remove 5 rows and then remove the 6th. The error does not have the minus sign, and if the minus sign is not on -c[1,5] then you will only have 5 rows and so the 6th will error.

# Remove the first 5 rows
output <- output[-c(1:5), ]

# Set the column headers using the 6th row
colnames(output) <- unlist(output[6, ])

# Remove the row used as headers
output <- output[-6, ]

thank you. though the code gives me an error : Error: R (1): Error in output[6, ] : incorrect number of dimensions
