マクロを使用して Excel セルに 2 次元バーコード (PDF417 または QR コード) を生成したいと考えています。これを行うための有料ライブラリに代わる無料の代替手段はありますか?
特定のツールで仕事ができることは知っていますが、それは私たちにとって比較的高価です.
VBAモジュールbarcode-vba-macro-only(コメントでSébastien Ferryが言及)は、2013年にMITライセンスの下でJiri Gabrielによって作成された純粋なVBA 1D / 2Dコードジェネレーターです.
コードは完全に理解できるものではありませんが、上記のリンクされたバージョンでは、多くのコメントがチェコ語から英語に翻訳されています。
ワークシートで使用するには、 barcody.basをモジュールの VBA にコピーまたはインポートします。ワークシートに、次のように関数を入れます。
=EncodeBarcode(CELL("SHEET"),CELL("ADDRESS"),A2,51,1,0,2)
使用方法は次のとおりです。
CELL("SHEET)
andはそのままにしておきますCELL("ADDRESS")
ワークシートで数式として使用するのではなく、純粋な VBA 関数呼び出しにするラッパー関数を追加しました。

このラッパーを使用すると、VBA でこれを呼び出すだけで、QRCode をレンダリングするために呼び出すことができます。
Call RenderQRCode("Sheet1", "A13", "QR Value")
ワークシート名、セル位置、QR_value を入力するだけです。指定した位置に QR シェイプが描画されます。
コードのこのセクションをいじって、QR のサイズを変更できます。
With xSheet.Shapes(QRShapeName)
.Width = 30 'change your size
.Height = 30 'change your size
End With
