Making of Webhooks for Sheets Workspace Add-on [and lessons learned using the Apps Script API]

Behind the scenes look at what went into creating an Apps Script-native Add-on to generate Webhooks for Google Sheets. ICYMI: You can access the add-on from this link and know more about what it does here

It’s worth checking out Sourabh Choraria’s latest Google Sheets add-on which enables users to quickly setup a Google Sheet to receive data from other services which support the creation of webhooks. As part of this solution the add-on makes extensive use of the Apps Script API, which can be used to programmatically manage Apps Script projects including deployments. This post from Sourabh highlights some of the key endpoints used in the Apps Script API as well as a number of lessons learned about deploying web apps for users.

Unnest an object with array values using cartesian product [for Google Apps Script POST/GET web apps]

Convert array values from the doGet & doPost event parameters into 2D array when writing them onto a Google Sheet.

Sourabh Choraria has hit a rich patch of Google Apps Script exploration and following the post we shared recently on Google Sheets cell precedents in this latest post Sourabh looks at restructuring data into a cartesian product. The post contains some nice other ‘Easter Eggs’, in particular, worth checking out Sourabh’s latest Workspace Add-on, Webhooks for Sheets, and a snippet of code on GitHub used in the add-on for handling GET and POST requests.

Find precedents of cells with formulas in Google Sheets using Apps Script — part 1

enumerate a range in google sheets using google apps script and use that to find precedents of cells that contain a formula.

Let’s start with the ubiquity of spreadsheets. I’ve long felt that spreadsheets were everywhere but until a post from Hjalmar Gislason I had never seen it in numbers and it made for interesting reading:

  • 1.2 billion people use Microsoft Office (WindowsCentral, March 2016), odds are most of them have at least access to Microsoft Excel.
  • Microsoft believes that 1 in 5 adults in the world use Excel (“What’s new in Microsoft Excel”, Sept 2017)
  • Excel is the number one skill mentioned in job ads, mentioned in approximately 1 in 3 job ads! (Indeed.com Job Trends, June 2017).
  • In 2010, RescueTime found that about 25% of computer users used Excel on a daily basis and that about 2% of all time spent on a computer anywhere was spent using Microsoft Excel.

As useful as spreadsheets are the underlying data structure can cause problems. This is covered in more detail in Patrick Burns’ Spreadsheet Addiction, which amongst other things highlights the ambiguity of value and formula:

Primarily the problem is that some cells have hidden meaning. When you see a number in a cell, you don’t know if that is a pure number or a number that is derived from a formula in the cell. While this distinction is usually immaterial, it can be critical.

The leading example is sorting. When rows are sorted, usually it is desired to sort the numbers as they are. However, it will be the formulas that are sorted. To humans the numbers are the primary thing, and the formulas are just something in the background. To the spreadsheet the formulas are primary, and the numbers are mere results.

This is a long winded way to highlight some work from Sourabh Choraria which is exploring how the relationship between formulas and cells can be extracted in Google Sheets. As part of this Sourabh is looking at how the getFormulasR1C1 method in SpreadsheetApp can be processed to find precedent cells. There are some very funky use of regex to parse formulas which is worth spending some time to digest.
