It is widely used in enterprise internal management, production process, logistics control system of the bar code system.
The below image displays Code128 barcode in a PDF document.
You can set Code128 in a worksheet using the following formula:
=BC_CODE128(value, color, backgroudColor, showLabel, labelPosition, codeSet, fontFamily, fontStyle, fontWeight, fontTextDecoration, fontTextAlign, fontSize, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom)
Name | Description |

value | A string that represents encode on the symbol of Code128. |
color | A color that represents the barcode color. The default value is 'rgb(0,0,0)'. |
backgroundColor | A color that represents the barcode backgroundcolor. The default value is 'rgb(255, 255, 255)' |
showLabel | Specifies whether to show label text when the barcode has label. |
labelPosition | A value that represents the label position when the label is shown. |
codeSet | A value that represents which code is set to use for QRCode. It has 'auto|A|B|C' values. The default value is 'auto'. |
