Example for from csv

Let's say we have the following file:

> cat pets.txt
animal, name, age
cat, Tom, 7
dog, Alfred, 10
chameleon, Linda, 1

pets.txt is actually a .csv file but it has the .txt extension, open is not able to convert it into a table:

> open pets.txt
animal, name, age
cat, Tom, 7
dog, Alfred, 10
chameleon, Linda, 1

To get a table from pets.txt we need to use the from csv command:

> open pets.txt | from csv
