Holt forecasting data excel

Hi,
I would like to proccesing data in excel. I am interested in forecasting in HOLT.
What I have to do ? step by step.

Do you mean R?
If so, how familiar are you with the R language?

You might want to have a look at the Task Views at https://cran.r-project.org/ to get some idea of what is available.

I suggest you read Chapter 8 in Forecasting: Principles and Practice, which is online (and free) at https://otexts.com/fpp3/

The book includes R code using the tidyverts set of packages, which is the next generation of the widely used {forecast} package by Rob Hyndman. I highly recommend it!

R of course. I will check .

thanks for answer . It sound good!

I am starting with R. I m looking some help to create a forecasting to library(Quandl). I am interested in ARIMA. Can you code to this one?
