Hi,

There is nothing built in to do ARIMA forecasting but you can use Excel's
functions or you can write code to do it.

Take a look at this:
Business Analysis with Excel 2nd Edition, Que, 2002, has VBA code that
calculates and charts a time series' ACFs and PACFs. Once you've identified
the ARIMA model you're in a position to create the forecast using Excel's
worksheet functions.
