[R] Converting .grib to excel file

[javad bayat]

Dear all;
I have downloaded meteorology data from "
https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=form"
as .grib format. It has hourly data of a complete year (every hour of every
day of 12 months) and has 6 meteorology parameters. The file has been
attached.
I am trying to convert it to an excel file that puts every parameter in a
separated column. For instance, the first col represents Date, 2nd
represents Temperature and so on.
Is there any way to do it?
I used these codes but did not work:
# install.packages("rNOMADS")

library(rNOMADS)

# Read GRIB data
grib_data <- ReadGrib("C:/Users/admin/Downloads/Met.grib")

# Convert to a data frame
grib_df <- as.data.frame(grib_data)

# Write the data frame to a CSV file
write.csv(grib_df, file = "output.csv")


I would be more than happy if anyone could help me.
Sincerely
