You can create a Code39 barcode using the BC_CODE39 function in a formula: =BC_CODE39(value, color, backgroundColor, showLabel, labelPosition, labelWithStartAndStopCharacter, checkDigit, nwRatio, fullASCII, fontFamily, fontStyle, fontWeight, fontTextDecoration, fontTextAlign, fontSize, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom).
The function has the following parameters:
value: this type must be a string that contains only numbers, uppercase letters, and symbols like '+', '-', '/', '$', and '%'.
labelWithStartAndStopCharacter: (default value is false) this value indicates whether to show the start and stop character in the label.
checkDigit: (default value is false) this value specifies if the symbol needs a check digit.
nwRatio: (default value is 3) this value represents the wide and narrow bar ratio, which can only be 2 or 3.
fullASCII: (default value is false) this value indicates if the bar code supports full ASCII.
