    In This Topic

    QRCode is a two dimensional barcode representing symbology that enables effective handling of numeric, alphanumeric and byte data. This barcode can encode up to 7,366 characters.

    The below image displays QRCode barcode in a PDF document.

    Formula definition

    You can set QRCode in a worksheet using the following formula:

    =BC_QRCODE(value, color, backgroundColor, errorCorrectionLevel, model, version, mask, connection, connectionNo, charCode, charset, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom)

    Note: The 'value' parameter is mandatory and the remaining ones are optional. This holds true for all the barcodes that support 'value' parameter in GcExcel.

    Parameter

    Name Description
    value A string that represents encode on the symbol of QRCode.
    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)'
    errorCorrectionLevel A string that represents the error correction level of QRCode. It has 'L|M|Q|H' four error correction levels. The default value is 'L'.
    model A value that represents the model of QRCode. It has 1 and 2 models. The default value is 2.
    version Vesion range is 1-14 for model1 and model 2. It has 'auto|1-14|1-40' values. The default value is  'auto'.
    mask A value that represents mask pattern for QRCode. It has 'auto and 0-7' eight mask pattern.
    connection A value that represents whether the symbol is part of a structured append message. The default value is false.
    connectionNo Specifies which block the symbol is in the structured append message. It has '0-15' values. The default value is '0'.
    charCode A value that represents the collection of characters of QRCode.
    charset A value that represents which charset to use. It has 'UTF-8 and Shift-JIS'.
    quietZoneLeft A value that represents the size of left quiet zone.
    quietZoneRight A value that represents the size of right quiet zone.
    quietZoneTop A value that represents the size of top quiet zone.
    quietZoneBottom A value that represents the size of bottom quiet zone.
