Harnessing the Power of QR Codes with Google Sheets
Updated: Apr 15
In today's digital-first world, QR codes serve as bridges between the physical and virtual realms, offering a seamless method to connect people with information, services, and each other. Originally developed in 1994 by Masahiro Hara for Denso Wave, a subsidiary of Toyota, to track vehicles during manufacturing, QR codes have transcended their initial industrial use to become a cornerstone of modern communication and marketing strategies. Compared to traditional barcodes, their capacity to store vast amounts of data has made them invaluable in our increasingly connected world.
The Resurgence of QR Codes
The practicality of QR codes has seen a significant resurgence, particularly highlighted by the global COVID-19 pandemic. Their contactless nature has proven to be an asset in maintaining social distancing guidelines, being utilised for everything from restaurant menus to ticketing and payments. Today, QR codes are omnipresent, facilitating a wide array of applications that include marketing campaigns, educational resources, event management, and much more.
A Guide to Generating QR Codes in Google Sheets
Google Sheets offers a versatile platform for generating QR codes, catering to both novices and experienced users through simple formulas and advanced scripting options. Here is a premade automatic QR Code generator template ready to go.
The FREE Solution: Quick and Easy QR Codes
One of the simplest ways to generate QR codes in Google Sheets is by using a formula; this formula, in fact:
=IMAGE("https://quickchart.io/qr?text=" & ENCODEURL(A2) & "&size=300")More on how this works later…
This method allows you to input a URL or any text in column A, with column B automatically displaying the corresponding QR code. This approach democratises access to QR code generation, making it accessible to anyone with basic spreadsheet knowledge.
A Note on Security
When utilising external data sources via the `IMAGE` function, Google Sheets will prompt a warning to ensure users are aware of the data exchange. This security measure is standard across the platform, aiming to protect users from unintended data sharing. For those interested in learning more about this feature and its implications, Google provides detailed documentation here.
In order to proceed and generate the QR code, you will need to click the ‘Allow access’ button, which will generate a QR image within the cell.
How does this formula work?
This formula combines several functions and operations to generate a QR code image within a cell dynamically. Here's a breakdown of each part:
1. `=IMAGE(...)`
Function - The `IMAGE` function in Google Sheets is used to insert an image into a cell. The image is displayed directly in the cell where the formula is entered.
Parameter - This function takes a URL that points to an image file on the internet. Optionally, it can also take a mode parameter that determines how the image is adjusted within the cell, but only the URL parameter is provided in this case.
URL Base - This is the base URL for generating QR codes using QuickChart, a service that provides APIs for generating charts and QR codes. The URL specifies the endpoint for QR code generation. QuickChart pricing can be found here, but the free solution allows 1,000 QR codes per month with unlimited scans and a limit of 60 QR codes per minute. This should suffice for most people's needs.
Parameters
`text=`: This parameter specifies the content you want to encode in the QR code. In the formula, the content is dynamically provided by concatenating the output of `ENCODEURL(A2)`.
3. `& ENCODEURL(A2) &`
Concatenation Operator (`&`) - This operator is used to join or concatenate strings and function results in Google Sheets. In this formula, it's used to concatenate the base URL, the URL-encoded content from cell `A2`, and additional parameters for the QR code.
`ENCODEURL(A2)` Function
Function - `ENCODEURL` is a function that URL-encodes a provided string. URL encoding converts characters into a format that can be transmitted over the Internet as part of a URL. This is necessary because URLs have a specific format and can only contain certain characters directly.
Parameter (`A2`) - The cell reference `A2` indicates the content that you want to encode into the QR code. This could be text, a URL, or any other data that the QR code should represent.
4. `"&size=300"`
Additional Parameter - This part of the URL specifies an additional parameter for the QR code generation:
`size=300`: Sets the size of the QR code image to 300x300 pixels. This parameter determines how large the QR code will be when generated.
Combined, the formula works as follows:
It starts with a base URL for the QuickChart QR code generation service.
It appends the URL-encoded content of cell `A2` to the `text=` parameter of the URL.
It specifies the size of the QR code to be generated.
The complete URL, which now points to a dynamically generated QR code image based on the content of `A2`, is passed to the `IMAGE` function.
The `IMAGE` function inserts the QR code image into the cell containing the formula.
This formula is an efficient way to generate and display QR codes directly in Google Sheets based on the data in your spreadsheet, providing a dynamic and visually engaging way to work with QR codes.
Advanced QR Code Automation
For those seeking a more sophisticated automated solution, a Google Apps Script-based method offers an advanced alternative. This approach generates QR codes and organises them in a dedicated 'QR Codes' folder within your Google Drive. Additionally, it updates the Google Sheets document with direct links to the QR code image in your Google Drive, providing a seamless integration between Sheets and Drive.
The good news is that this Advanced QR Code Generator is available as a template, so no knowledge of Google Apps Script is required to use this; you can pick yours up below.
Advantages of the Advanced QR Code Generator
The Advanced QR Code Generator solution brings several key benefits over the free method, including:
Automation - Automatically generate QR codes for multiple entries, saving time and reducing manual effort.
Organisation - Keep all QR codes neatly stored in a designated Google Drive folder, facilitating easy access and management.
File Format - QR Codes are conveniently saved as images to be used anywhere.
Integrated Experience - Enjoy a seamless workflow within the Google ecosystem, enhancing productivity and efficiency.
This advanced solution is particularly beneficial for users managing large volumes of QR codes, such as in event management, education, or marketing. The automation and organisational features provided by the script significantly streamline the process, offering a compelling value proposition for those looking to optimise their workflows. Since this script generates images and saves them in your Google Drive, they can be used anywhere, such as in emails, on business cards and posters, and anywhere else you can use an image.
The same limitations apply to the number of QR codes you can generate using the QuickChart API; pricing can be found here. The free solution allows 1,000 QR codes per month with unlimited scans and a limit of 60 QR codes per minute. This should suffice for most people's needs even with automation in Google Sheets with this template.
Conclusion
QR codes have become integral to our digital landscape, offering a versatile tool for linking the physical and digital worlds. Google Sheets presents a powerful platform for generating these codes, catering to a range of needs from simple, formula-based solutions to advanced, script-driven automation.
