CSV Insert Column

See more CSV Examples

Insert a new column into an existing CSV.

Note: This example requires Chilkat v9.5.0.89 or greater because the InsertColumn method was added in v9.5.0.89.

Go

    success := false

    csv := chilkat.NewCsv()

    // Load the following CSV:

    //  Name;City;Weight
    //  John;Chicago;180
    //  Lisa;Denver;120

    // Indicate that the 1st line contains column names.
    csv.SetHasColumnNames(true)
    success = csv.LoadFile("qa_data/csv/insertColumnTest.csv")

    // We can insert a column before the 1st column.
    csv.InsertColumn(0)

    fmt.Println(*csv.SaveToString())

    // The CSV now looks like this:

    //  ;Name;City;Weight
    //  ;John;Chicago;180
    //  ;Lisa;Denver;120

    // Set the cells in column 0.

    col := 0
    csv.SetColumnName(col,"id")
    csv.SetCell(0,col,"100")
    csv.SetCell(1,col,"101")

    fmt.Println(*csv.SaveToString())

    // We now have:

    //  id;Name;City;Weight
    //  100;John;Chicago;180
    //  101;Lisa;Denver;120

    // Insert a new column between City and Weight
    // In other words, add a new column before the Weight column.
    weightColumn := csv.GetIndex("Weight")
    fmt.Println("Weight Column Index = ", weightColumn)
    csv.InsertColumn(weightColumn)

    fmt.Println(*csv.SaveToString())

    // We now have:

    //  id;Name;City;;Weight
    //  100;John;Chicago;;180
    //  101;Lisa;Denver;;120

    // Set the cells in the new column:

    csv.SetColumnName(weightColumn,"Height")
    csv.SetCell(0,weightColumn,"6' 2\"")
    csv.SetCell(1,weightColumn,"5' 7\"")

    fmt.Println(*csv.SaveToString())

    // We now have:

    //  id;Name;City;Height;Weight
    //  100;John;Chicago;"6' 2""";180
    //  101;Lisa;Denver;"5' 7""";120
