csv-pair

Combines two CSV files merging identical columns

NPM Build status semantic-release

Example: combine two CSV files. Some columns are identical, some are different

a.csv

name,age,occupation
John,20,student
Mary,21,student

b.csv

name,age,occupation
John,20,teacher
Mary,21,doctor

Let us combine these two CSV files. Identical columns will be collapsed. Different values will have duplicate column

csv-pair a.csv b.csv combined.csv

combined.csv

name,age,occupation - a.csv,occupation - b.csv
John,20,student,teacher
Mary,21,student,doctor
