使用Excel VBA生成2D（PDF417或QR）条形码

本文介绍了使用Excel VBA生成2D（PDF417或QR）条形码的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我想在Excel单元格中使用宏生成2D条形码（PDF417或QR码）。只是想知道付费图书馆是否有免费的替代方法？ 我知道某些工具可以做这项工作，但对我们来说比较贵。解决方案 VBA模块 barcode-vba-macro-only 代码不完全简单易懂，但很多意见已经从捷克语翻译成英文版本，链接到上面。 要在工作表中使用它，只需复制或导入 barcody.bas 插入到一个模块中的VBA中。在工作表中，输入如下功能： = EncodeBarcode（CELL（SHEET），CELL（ADDRESS ），A2,51,1,0,2） 使用方法如下： 保留 CELL（SHEET）和 CELL（ADDRESS ）因为它是只是引用工作表和单元格地址，你有公式 A2是您的字符串要编码的单元格，在我的情况下，它是单元格A2您可以使用引号将Text传递给相同的使单元格使其更加动态 51是QR码的选项，其他选项为1 = EAN8 / 13 / UPCA / UPCE，2 =五个交错中的两个，3 = Code39,50 =数据矩阵，51 = QRCode 1用于图形模式，条形码绘制在Shape对象上，字体模式为0，假设您需要安装字体类型。 没有用。 0是特定条形码类型的参数。对于QR_Code，0 =低误差校正，1 =中等误差校正，2 =四分位错误校正，3 =高纠错。 2仅适用于1D代码。这是缓冲区。我不确定它是做什么，但可能与 1D条形空间有关？ 我添加了包装函数，使其成为纯VBA函数调用，而不是将其用作工作表中的公式： Public Sub RenderQRCode（workSheetName As String，cellLocation As String，textValue As String） Dim s_param As String Dim s_encoded As String Dim xSheet As Worksheet Dim QRShapeName As String Dim QRLabelName As String s_param =mode = Q s_encoded = qr_gen（textValue，s_param ）调用DrawQRCode（s_encoded，workSheetName，cellLocation） 设置xSheet =工作表（workSheetName） QRShapeName =BC& $&左（cellLocation，1）_ & $& Right（cellLocation，Len（cellLocation） -

Just wondering is there any free alternatives to paid libraries to do this?I know certain tools can do the job but it is relatively expensive to us. 解决方案 The VBA module barcode-vba-macro-only (mentioned by Sébastien Ferry in the comments) is a pure VBA 1D/2D code generator created by Jiri Gabriel under MIT License in 2013.The code isn't completely simple to understand, but many comments have been translated from Czech to English in the version linked above.To use it in a worksheet, just copy or import barcody.bas into your VBA in a module. In a worksheet, put in the function like this:=EncodeBarcode(CELL("SHEET"),CELL("ADDRESS"),A2,51,1,0,2)The usage is as follows:Leave the CELL("SHEET) and CELL("ADDRESS") as they are since it'sjust giving reference to the worksheet and cell address you have theformulaA2 is the cell that you have your string to be encoded. In my case it's cell A2 You can pass "Text" with quotes to do the same.Having the cell makes it more dynamic51 is the option for QR Code. Other options are 1=EAN8/13/UPCA/UPCE, 2=two of five interleaved, 3=Code39, 50=DataMatrix, 51=QRCode1 is for graphical mode. The barcode is drawn on a Shape object. 0 for font mode. I assume you need to have the font type installed.Not as useful.0 is the parameter for the particular barcode type. For QR_Code, 0=Low Error Correction, 1=Medium Error Correction, 2=Quartile errorcorrection, 3=high error correction.2 only applies to 1D codes. It's the buffer zones. I'm not certain what it does exactly but probably something to do with the1D bar spaces?I added wrapper functions to make it a pure VBA function call rather than using it as a formula in a worksheet:Public Sub RenderQRCode(workSheetName As String, cellLocation As String, textValue As String) Dim s_param As String Dim s_encoded As String Dim xSheet As Worksheet Dim QRShapeName As String Dim QRLabelName As String s_param = "mode=Q" s_encoded = qr_gen(textValue, s_param) Call DrawQRCode(s_encoded, workSheetName, cellLocation) Set xSheet = Worksheets(workSheetName) QRShapeName = "BC" & "$" & Left(cellLocation, 1) _ & "$" & Right(cellLocation, Len(cellLocation) -
