NAME

csvio - facilities for reading and composing Comma-Separated-Values (CSV) data with awk.

SYNOPSIS

@include “csvio”
csvimport([comma [, quote]])
result = csvrecord(afield [, comma [, quote]])

DESCRIPTION

The csvio.awk library provides functions for reading and composing CSV data records:
csvimport([comma [, quote]])

Converts the input CSV record into a regular awk record delimited by OFS. Automatically collects additional iput lines to complete the current input record if it contains EOLs embedded in fields.

	comma		Optional. The CSV input field delimiter. Default comma (’,’).
	quote		Optional. The CSV input quoting character. Default double quote (’"’).

csvrecord(afield [, comma [, quote]])

Returns a CSV formatted string by composing the values in the afield array. If afield has a null value, compose the values of the current fields $1 to $NF.

	afield		An array of field values, indexed from 1 to N.
	comma		Optional. The resulting CSV field delimiter. Default comma (’,’).
	quote		Optional. The resulting CSV quoting character. Default double quote (’"’).

EXAMPLES

Import CSV data:

echo '007,"Bond, James",United Kingdom' | gawk '
@include "csvio"
BEGIN {FS=OFS="|"}
{ csvimport()   # --> $0 = "007|Bond, James|United Kingdom"
}'

Compose from an array of field values:

f[1] = "007"
f[2] = "Bond, James"
f[3] = "United Kingdom"
result = csvrecord(f)  # --> '007,"Bond, James",United Kingdom'

Compose from the current field values:

FS=OFS="|"
$0 = "007|Bond, James|United Kingdom"
result = csvrecord()  # --> '007,"Bond, James",United Kingdom'

BUGS

CSV fields with embedded EOLs are not supported when reading with redirected getline.
