(JavaScript) CSV Column Names

Demonstrates how to access CSV column names.

The Chilkat CSV library/component/class is freeware. The downloads for .NET, C++, Perl, Java, Ruby, and Python contain all of the Chilkat classes, some of which are freeware and some of which require licensing.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example program loads a file (sample.csv)
// that contains this content:
// 
// year,color,country,food
// 2001,red,France,cheese
// 2005,blue,"United States",hamburger
// 2008,green,Italy,pasta
// 1998,orange,Japan,sushi
// 
// The first row contains the column names.
// This file is available at:
// http://www.chilkatsoft.com/testData/sample.csv

var csv = new CkCsv();

// Prior to loading the CSV file, indicate that the 1st row
// should be treated as column names:
csv.HasColumnNames = true;

// Load the CSV records from the file:

success = csv.LoadFile("sample.csv");
if (success !== true) {
    console.log(csv.LastErrorText);
    return;
}

// Display the column names:
var i;
var colName;
var idx;
for (i = 0; i <= csv.NumColumns - 1; i++) {
    colName = csv.GetColumnName(i);
    console.log(i + ": " + colName);

    // The following line demonstrates to to get the column
    // index given a column name:
    idx = csv.GetIndex(colName);
    console.log(colName + " is at column index " + idx);
