EAN-13

EAN-13 barcode makes use of numeric characters (twelve numbers) and a check digit. This barcode accepts only twelve numbers as a string to calculate a check digit (CheckSum) and adds it to the thirteenth position. The check digit is an additional digit that can be used to verify that the barcode has been scanned accurately. When the CheckSum property is set to True, the check digit is automatically added. This is mainly used in supermarkets and other retail businesses.

Formula definition

You can set EAN-13 barcode in a worksheet using the following formula:

=BC_EAN13(value, color, backgroundColor, showLabel, labelPosition, addOn, addOnLabelPosition, fontFamily, fontStyle, fontWeight, fontTextDecoration, fontTextAlign, fontSize, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom)

Note: The 'labelPosition' parameter can only be set to top or bottom. This holds true for all the barcodes that support 'labelPosition' parameter in GcExcel.

Parameter

Using Code

This example code sets EAN13 in the worksheet.

// Create a new workbook
var workbook = new GrapeCity.Documents.Excel.Workbook();

// Set worksheet layout and data
IWorksheet worksheet = workbook.Worksheets[0];
worksheet.Range["B:C"].ColumnWidth = 15;
worksheet.Range["D:G"].ColumnWidth = 20;
worksheet.Range["4:7"].RowHeight = 60;
worksheet.Range["A:A"].ColumnWidth = 5;
worksheet.Range["B2"].Value = "EAN-13";
worksheet.Range["B2:F2"].Merge(true);
worksheet.Range["B3:G3"].Value = new object[,]{
    {"Name", "Number", "Defult", "Change addOn", "Change addOnLabelPosition", "Explain"}
};
worksheet.Range["B4:C7"].HorizontalAlignment = HorizontalAlignment.Center;
worksheet.Range["B4:C7"].VerticalAlignment = VerticalAlignment.Center;
worksheet.Range["B2:F3"].HorizontalAlignment = HorizontalAlignment.Center;
worksheet.Range["B2:F3"].VerticalAlignment = VerticalAlignment.Center;
worksheet.Range["B4:C6"].Value = new object[,]
  {
    {"Medicine", "692031229621"},
    {"Pen", "6945091701532"},
    {"value length is 13", "8142486545683"}
  };
worksheet.Range["G6"].Value = "No EAN-13 generated, because the last digit is check-sum digit and it is invalid";
worksheet.Range["G6"].Font.Color = Color.Red;
worksheet.Range["B4:C6"].WrapText = true;
worksheet.Range["G6"].WrapText = true;
worksheet.PageSetup.Orientation = PageOrientation.Landscape;
worksheet.PageSetup.PrintGridlines = true;

// Set formula
for (var i = 4; i < 7; i++)
{
   worksheet.Range["D" + i].Formula = "=BC_EAN13" + "(C" + i + ")";
   worksheet.Range["E" + i].Formula = "=BC_EAN13" + "(C" + i + ",,,,,22)";
   worksheet.Range["F" + i].Formula = "=BC_EAN13" + "(C" + i + ",,,,,22,\"bottom\")";
}

// Save to a pdf file
workbook.Save("ean13.pdf");
