The charts themselves are a bit of a novelty. Yes, they’re aesthetically pleasing because of that resemblance to a real-world, tapering funnel, which reinforces their message, but a plain ole’ bar chart would be equally suitable and actually easier to read data from (because the bars have a common baseline).
However, they throw up some interesting techniques in Google Sheets and for that reason, merit this long article.
We’ll build them using tricks with the chart builder tool, then with two different types of funky formula and finally, and best of all, we’ll build a tool using Apps Script, as shown in this image:
As with the waterfall charts in Google Sheets, they’re not one of the out-the-box charts available to us, so we have to manually create them with a crafty workaround. Thankfully, they’re relatively simple to create, certainly simpler than the waterfall chart.
For all of these examples, we’ll use this fictitious real-estate dataset:
Here, I’m imagining the real estate agency collects data relating to their sales funnel, and they want to display it in a funnel chart format.

Sparklines are small, lightweight charts, typically without axes, which exist inside a single cell in your spreadsheets. They’re a wonderful, quick way to visualize your data, without needing the complexity of a full-blown chart.
They were first created by interface designer Peter Zelchenko around 1998. The term “sparkline” was coined by statistician and data visualization legend Edward Tufte.
This year The Writer’s Bundle 2015 was bigger and better than ever, so I wanted to create an even more useful dashboard for the team. The dashboard was a key tool for the team, to monitor both overall and individual sales channel performance, as well as to be a motivating force by giving everyone a visual sense of progress.
The idea originated from discussions with my wife about the tedium of preparing month-end website performance reports for her content management clients. This dashboard was a solution to streamline the monthly web reporting and offer insights that might otherwise be missed. Rather than having to visit Google Analytics for each website in turn and click around gathering the necessary data, this pulls it all together in one place.
