Macro to copy data from one worksheet to another

Hi,

I would like to create a macro that allows me to copy data from a one worksheet to another in the same XL document. Attached is an example of what I'm trying to do.

I have data from a market survey on people who have bought different types of coffee - see attached (this is not the real data; I have reproduced something just for the purpose of this question; in my real data I have ~18000 rows and >80 columns). I need to do an analysis for all respondents and then repeat the same analysis but for each different type of product bought. At the end, I would like to have one worksheet for each type of coffee bought.

My idea is
1) do the analysis with pivot tables in Analysis Master Sheet for all products bought
2) use the macro to copy the data into the "All Products" worksheet
3) change cell (B,1)in Analysis Master Sheet to the next product type (e.g. Caffee Latte)
4) use the macro to copy the data into the "Caffee Latte" worksheet
5) etc...

[BTW - if you think this is a daft idea and there is a much easier way... feel free to let me know]

Can anyone help me with the macro? I have never written one, so assume I know nothing about macros.

Thanks for any help
Kind regards,
Laurent
