CSV Column Names

See more CSV Examples

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.

Swift

func chilkatTest() {
    var success: Bool = 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

    let csv = CkoCsv()!

    // 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(path: "sample.csv")
    if success != true {
        print("\(csv.lastErrorText!)")
        return
    }

    // Display the column names:
    var i: Int
    var colName: String?
    var idx: Int
    for i = 0; i <= csv.numColumns.intValue - 1; i++ {
        colName = csv.getColumnName(index: i)
        print("\(i): \(colName!)")

        // The following line demonstrates to to get the column
        // index given a column name:
        idx = csv.getIndex(columnName: colName).intValue
        print("\(colName!) is at column index \(idx)")
    }
