from-csv

Converts csv data into table. Use this when nushell cannot dertermine the input file extension.

Example

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
━━━┯━━━━━━━━━━━┯━━━━━━━━━┯━━━━━━
 # │ animal    │  name   │  age
───┼───────────┼─────────┼──────
 0 │ cat       │  Tom    │  7
 1 │ dog       │  Alfred │  10
 2 │ chameleon │  Linda  │  1

To ignore the csv headers use --headerless :

━━━┯━━━━━━━━━━━┯━━━━━━━━━┯━━━━━━━━━
 # │ Column1   │ Column2 │ Column3
───┼───────────┼─────────┼─────────
 0 │ dog       │  Alfred │  10
 1 │ chameleon │  Linda  │  1
