Ever wanted to play with QR codes in a spreadsheet and not download anything or send your data to the internet? Now you can.
I added an #excel #spreadsheet to do a version 15 QR code generation, all error correction levels. (77x77 pixels)
Everything is done inside the spreadsheet and totally transparent—data arrangement, error correction calculations, everything.
No add-ins, no macros, no array formulas. The spreadsheet doesn’t send your data anywhere.
Have fun with it, break it, let me know if you do. My next mod to the spreadsheet is to have it produce all QR code versions; the basics are already in the spreadsheet so hopefully it isn’t too much more work.
Just throwing this out there
