问题
I have a simple question about generating QR codes with google-spreadhseet. I am using google's API call
=image("https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl="&A3)
This works fine.
Where A3 is a persons first name.
I have their last name in A4 but when I try:
=image("https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl="&(A3+A4))
or
=image("https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl="&
(CONCATENATE(A3, " ", A4)))
The QR box is blank.
How can I generate a QR code from both the first and last name without having to create another field.
回答1:
Simple as that:
=image("https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl="&A3&A4)
Note that this will only work if A3 and A4 only contain unreserved URL characters; otherwise you need percent encoding as explained in another answer here.

See this other post which gives a full explanation on how to encode data to create the QR code and gives an example on how to take information row by row from a sheet and automatically build QR codes.
