I have a set of records (excel file) with customer and subscription details. For every customer, based on the order date, I would like to see who made a different product purchase.

for eg:

I would like to come to a conclusion that Customer A bought different products. ( or just a count of how many people went on to purchase different products) Further on, I would also like to know how many went on to buy product Y from product X.

In SQL, it would be something like this:

Partition by Customer, Order by date,

select customer with count(product)>1

My objective is to analyse customer journey and I would like to hear any suggestions or recommendations on the best way to do it.
