Ever find yourself needing to repeat an action in your Google Sheets?
For example, on a recent client project I wanted to cycle through my spreadsheet data, compare it to another dataset and apply a matching algorithm. To do this and stay within the 6 minute execution limit for Apps Script, I split my data into “blocks” of 10 rows, counted how many blocks I had and then ran the matching algorithm once for each block until they’d all been processed.
By adding time-based triggers, I setup my Google sheet to do this automatically, rather than having me click a button each time.
In this post I’m going to show a skeleton example of this time-based architecture, to which you can add your own functionality.
The entire code file is here on GitHub and the spreadsheet is available here (feel free to make a copy: File > Make a copy… and then you can open the script editor to modify the code).
Time-based triggers with Google Apps Script
In this simple example, I’m going to output a random number in a new line of my spreadsheet every minute until I’ve looped through a set number of times (2 in this case). It’s deliberately basic as the focus is on the trigger/timing architecture.
Here’s a screencast of this simple program in action (speeded up):
Behind the scenes, everything is running on autopilot once I’ve clicked that first Run button.
Here’s a collection of resources for you: a strange mix of advanced, esoteric and inspirational spreadsheet uses, showing how far some (mad)men and women push their spreadsheets. The list gets more light-hearted towards the bottom of the post!
Somehow I doubt Dan Bricklin would have envisioned all this when he invented the spreadsheet…
Functional programming in Excel from Felienne Hermans all about her research into treating Excel as programming language. Well worth a watch.
Google launched a new business intelligence tool called Data Studio in May 2016. It’s a really smart reporting tool for quickly creating powerful, stunning dashboards from multiple Google data sources.
It’s a great option for small/medium businesses already using Google tools, who want to build bespoke dashboards for that 40,000ft view of their business.
Google Data Studio Example Reports
Here are two example reports for a mid-size website (~500k pageviews a month).
Regular readers will know of my enthusiasm for building dashboards, especially using Google apps (like this one or this how-to article).
So I was super excited in May of this year when Google launched Data Studio, a free data visualization and dashboard tool to compete against incumbent dashboard vendors Microsoft PowerBI, Tableau and Qlickview.
Here, I’m excited to share my initial impressions and show you some of the basics steps to build dashboard reports using this tool.
In the following image, I have two browser windows open. On the left, a Google Sheet containing a simple table of data. In the right browser window, a web page with a d3 chart that displays the data from the Google Sheet and can be refreshed dynamically when the data changes.
