![]() ![]() width (optional): Set the image width in pixels where the sizing argument is set to 3.height (optional): Set the image height in pixels where the sizing argument is set to 3.2: Keep the original image size, even if it is outside the cell.1: Stretch or squeeze the image to fill the cell.0: Fit the image in the cell and maintain the aspect ratio.sizing (optional): A setting to represent how the image size should be set:.alt_text (optional): The text to describe the image for accessibility purposes.The image function has the following syntax. If combined with a service like QuickChart, we can create dynamic QR codes in Excel. Since late 2022, Excel 365 and Excel Online users have had the IMAGE function. Create QR codes with the IMAGE function (Excel 365) If the image covers too much of the code, it may fail to operate correctly. Note: If using a center image, test the result to ensure the QR code works. ![]() centerImageSizeRatio: the % of space taken up by the center image.centerImageURL: the URL of an image to include in the center of the QR code.ecLevel: the amount of error correction, valid entries are L, M, H, Q (default is M, or H if QR code includes an image).light: the hex color of the light cells & margin (default is #ffffff).dark: the hex color of the dark cells (default is #000000).size: the image size in pixels (default is 150).margin: the amount of white space around the QR code (default is 4).Here is a selection of those parameters, which we use in the next section. ![]() QuickChart.io has lots of additional parameters for generating the QR codes. The section after text= is the text embedded in the QR code. For example, the URL below generates the QR code. With QuickChart, we only need a URL with the correct syntax to generate a QR code. We are using QuickChart.io, but others are available, such as, and the google API. If the designer QR code can still be read, you are on the safe side.All the methods in this post use an online service to generate the QR code image. Basically, you should always test with a smartphone with a poor camera and apps with weak decoding algorithms. Test, Test, TestĪt each design step, test whether the QR code is still readable and only after then add a new design element.Īlso note that not all QR code readers can decode the Designer QR code equally well. How well a QR code can be read also varies from app to app and algorithm to algorithm. ![]() Designer QR codes are more difficult to decode, so the scan position, the angle of the camera to the QR code and how far the camera is from the QR code matters. The less complex the QR Code, the easier it is to decrypt it. The safest variant that a QR code can be read by all readers, is the Standard QR Code.
