Where can I find detailed stock prices for the past year. (x-post from Investing)

I want to preface this and say that I am new to investing and I apologize if my question isn't clear.

Is there a way for me to find minute-by-minute stock prices for the past year? Including extended hours. Preferably, this data will be in excel form and easily searchable. Can I do the same for gold and silver prices?
