Nice ! I found another site which actually gives you a link to the generated QR Code, so that I donā€™t have to worry about storage of the codeā€¦ [https://api.qrserver.com/v1/create-qr-code/?size=300x300&data=YOURQRDATA](https://api.qrserver.com/v1/create-qr-code/?size=300x300&data=YOURQRDATA) ---

I was tried @Killko solution. Itā€™s work on google sheets. ![Screen Shot 2021-01-20 at 10.54.03 AM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/8/7/870f9ac9854c053ba23d61e3651a3828b8bfa35f.png) But I canā€™t display it on the app. ![Screen Shot 2021-01-20 at 10.55.06 AM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/c/c/cc18b0c976a91cecb395c2854a38821b94e5f946.png) How can you do that? @Fredibu ---

Seems like youā€™re using an image formula in the Sheet. You would need an actual link (without the image function) for Glide to read and display it. ---

Hi @PaulVu, my initial way didnā€™t display because the google api gives you an image rather than a link to the QR Code. I found another QR Code api that works like a charmā€¦ Change : =ARRAYFORMULA(IF(E2:E="","",ā€œ[https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=ā€&F2:F](https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=%E2%80%9D&F2:F))) to =ARRAYFORMULA(IF(E2:E="","",ā€œ[https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=ā€&F2:F](https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=%E2%80%9D&F2:F))) ---

You can also generate QR codes using [quickchart.io](https://quickchart.io/documentation/#qr) Rather than using an arrayformula in the Google Sheet, Iā€™d recommend using a template column in Glide. ie. something like this: ![Screen Shot 2021-01-20 at 7.50.28 PM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/c/a/caaeaf18567bf5c75f3a2ac90608151729498f56.png) ---

Iā€™ve always wondered about which was more efficient. Do you have data about this ? ---

For me, itā€™s less about efficiency, and more about avoiding spreadsheet formulas where ever possible. That said, any time youā€™re doing calculations in the spreadsheet, youā€™re always going to see a delay due to the time it takes to sync changes. In this case that might not be an issue, but often it is if you need instant results. But again, I just use a general rule of thumb - only do it in the spreadsheet if it canā€™t be done in Glide. ---

Hi @Killko , I learned the hard way about QR codes generated in the Google sheet. The load times became really slow for the app & I had around 700 to a 1000 members rows with QR code spreadsheet formula. David advised me to create the template column in the Glide table & remove the spreadsheet array formula & it helped speed the app up. So definitely do the QR code generation in the glide tables.

Could we do this with the new Webhook action in Glide by any chance? ---

Hello ! Can you purge google sheet rows ? We cannot get your template to learn because its exceeds the limit for duplicating the app. Thank you. ---

@MGD_Tecnologia you could have a go - I did manage to copy the app today. I did clean up quite a few rows [Previous page](https://community.glideapps.com/t/qr-code-scanner-demo/11620.md?page=1)
