QR Codes for Excel 2003 XP

Hi

Anyone know of any software (free or commercial) that can allow Excel to systematically convert text to QR Code? THere are web based solutions but I need for Excel to convert hundreds of items in one go.

Many thanks

Damian

@KH

Thank you for sharing !! :))

Kenneth,

I have never had a need for many QR codes so one of the generators around work fine for me, but I tried this and couldn't figure out how to get true multi-lines. Any idea what to inject into the text so as to get a business card to spread over multi-lines?

I would just treat it as a graphic and insert it where needed. One can compute the size in terms other than pixels if a set size is needed to span multiple lines. Are you doing the card in an MSWord file or Excel?

Not sure that we are on the dame page. I was referring to creating a QR from a text string of my business details. I just adapted your code in Excel and fed the details to it. It worked fine insofar as a QR is created and when I read that QR all the information is there, except that it came out as lone continuous line, not multiple lines for each data element.

It is not important, as I have a QR image of my details from elsewhere, just tried it out of interest.

I don't have a smart phone so I can not test that. I have always used the QR as a link to a web site. For that, I usually use is.gd's QR code since I typically need to shorten the link for other needs. I then clip the QR code image.

Without seeing your coded string, I would guess that it might mean that you used vbLF rather than vbCRLF to build the string for it?

I tried them all Kenneth, vbLf, vbCrLf, and vbNewline - none achieved the breaks. As none of those worked, I even tried embedding %0A and %0D in case the API accepted those, but no joy.

Since vbCR = decimal character 13 = hex D or &HD
and
vbLF = decimal character 10 = hex A or &HA
vbCRLF = decimal characters 13 and then 10.

xld was close. We just need to escape those characters for html.
"%0D%0A"

e.g.
[vba]Sub Test2_DownloadQRcode()
DownloadQRcode "Hello World!" & "%0D%0A" & "by Kenneth Hobson", "c:\temp\HelloWorld.png", 360
Shell "cmd /c ""c:\temp\HelloWorld.png"""
End Sub[/vba]
