Hi folks
I thought this would be much simpler than it has turned out, so as ever..... I need help please.
OK, what I want sounds simple, I'd just like to have cells in a column of values (eg 21166985-48-14580) and on rows where the column isn't empty, create in the next adjacent column the text as a QR code. So for example, if cell A1 contained the value "1234", then B1 would have a QR code for 1234, if A2 value is "STUMPED" then B2 would be QR for "STUMPED"... which I am. I thought it would be as simple as a basic bar code where I could just use a font, but not so for QR codes. It needs to be a QR, as I might have up to 16 or 17 characters, which creates too long a linear bar code. I have tried the info I found on Mr Excel QR code generator modification, but that only creates a QR code from a single cell input, not something that will create what I need from a column of values.
Is it possible to alter that code to do something more, it's way too complicated for my meagre ability, or is there something much simpler?
Thanks
 

Excel Facts

Did you know Excel offers Filter by Selection?
Add the AutoFilter icon to the Quick Access Toolbar. Select a cell containing Apple, click AutoFilter, and you will get all rows with Apple
Maybe the below will help:
VBA Code:
Sub GenerateQR()
    Dim URL As String
    Dim PlaceAtCell As Range
    Dim rCell As Range
    Dim pNum As Long
    
    For Each rCell In Range("A2:A" & Range("A" & Rows.Count).End(xlUp).Row).Cells
        pNum = pNum + 1
        URL = "https://barcode.tec-it.com/barcode.ashx?data=" & rCell.Value & "&code=EPCQRCode&eclevel=M"
        ActiveSheet.Pictures.Insert(URL).Name = CStr(pNum)
        Set PlaceAtCell = rCell.Offset(, 1)
        With ActiveSheet.Pictures(CStr(pNum))
            .ShapeRange.LockAspectRatio = msoTrue
            .Left = PlaceAtCell.Left + 1
            .Width = PlaceAtCell.Width - 1
            .Top = PlaceAtCell.Top + 1
            .Height = PlaceAtCell.Height - 1
        End With
    Next rCell
End Sub

Thanks Georgi
I'm on my way home now, and I'll try that later. I was hoping for something that didn't require internet connection, but I won't rule anything out yet.....
Appreciate your time , thank you

Hi all,
if you need a solution working without an internet connection, the best way is to use a third-party software. Here is an example using SimpleCodeGenerator, a free tool that doesn't require installation, available here:
Just adjust the path in the code
VBA Code:
Sub GenerateQR_NirSoft()
    
'https://www.mrexcel.com/board/threads/qr-codes-again.1224859/post-5991315
    
Dim S               As String, GenPath As String, destPath As String, MyText As String, dQ As String
Dim LastRow         As Integer, i As Integer
Dim Pic             As Object
Dim pNum            As Long
    
GenPath = "C:\Users\Sequoyah\Desktop\SimpleCodeGenerator.exe /ErrorCorrection 4 /MinVersion 1 /MaxVersion 40 /Clipboard " '<<==== Adjust th PATH

LastRow = Range("A" & Rows.Count).End(xlUp).Row
dQ = """"

Application.ScreenUpdating = False

'delete old pic. from cells
For Each Pic In ActiveSheet.Pictures
    If Not Intersect(Pic.TopLeftCell, Columns("B")) Is Nothing Then Pic.Delete
Next Pic

For i = 2 To LastRow
    pNum = pNum + 1
    MyText = " " & dQ & Range("A" & i).Value & dQ & " "
    S = GenPath & MyText & "5"        'Image Size
    
    Shell (S)
    
    With ActiveSheet
        .Paste Destination:=.Range("B" & i), Link:=False
        .Pictures(.Pictures.Count).Name = CStr(pNum)
    End With
    
Next i

End Sub

Hi folks
Sorry for delay. Weekend got me :)
OK, tried both with varying results.

Georgi, thank you, I tried that but after running it a couple of times it said I had exceeded the limit from the website, and also added a whole heap of text in the cells where there was no text to convert. This will be an ongoing usage and quite large, so not sure that will work long term.

Sequoyah, thank you also, I just couldn't get that to function at all. I'm obviously doing something stupid. I saved the .exe file on my desktop, copied and pasted your filepath into the code, obviously replacing the start with the filepath from my pc, but nothing would happen at all, even if I tried to run directly from in the VBA window, just nothing.

I have, however, come across a third offering (I've looked in so many places, I don't know where I found this now) which is almost perfect. It does still run from the internet, so not sure if that will cause an issue in the future. It works fine except that every time it runs, it runs for the entire sheet and so creates a duplicate image on top of the previous images, which will just keep increasing. Could anyone see a way in which it will only create an image for cells that do not already contain one? So only for new entries? I've developed the sheet loosely to show a little more of my thinking in actual use. The QR code will actually contain a part number, quantity and unique serial number.

Solution
In hindsight, this will work perfectly. Now I have a way to easily create one, and giving the working sheet more thought, I don't need to keep all of the QR codes. I'll be using this WB to create labels, so only need to create one QR code at a time for printing and just have a table of the text going into the code.
I think I am solved for now, thank you both for your suggestions

I'm not sure which "this" you are referring to but if it is one of the earlier posts then mark that post as the solution to help future readers.
I have removed the solution mark from post #6 as that doesn't actually contain the solution. :)

Hi Peter
Sorry if that was misleading. Post 5 is the solution I'm currently working with for my purposes. It's not perfect, but with my meagre skills it's the one I'm finding easiest to achieve my end result so far..... I'll more than likely be back once I've found something else to confuse me.
:)
