I have several csv files with no headers and the only commonality is the first column that always has the users unique ID. I want to create one csv file that combines specific information based on the user ID chosen.
So for example there is:
table 1 (which has no header but for guidance the columns are ID, Name, Birthday)
80938 James Nov-00
78397 Tom Jul-20
73820 Pam Sep-10
and table 2 (which has no header but for guidance the columns are ID, Product Category, Purchase in 2012, Purchase in 2013, Purchase in 2014, Purchase in 2015)
80938 1 500000 600000 700000 800000
80938 2 333 456 567 467
80938 3 444 456 399 799
I want to create the combined table below
ID: 80938
Name: James
Birthday: Nov-00
Product: 1
2012 2013 2014 2015
Purchase 500000 600000 700000 800000
