Did you know you can actually code in Google Sheets?

Did you know you can actually code in Google Sheets? While many people think of Google Sheets as just a place to crunch numbers and organize data, there are actually two powerful ways to harness the power of coding within it.

Coding in Google Sheets can be approached in two main ways: using Apps Script, a JavaScript-like language, or by working with formulas directly inside Google Sheets cells. While some might not consider using formulas as "coding," they can become incredibly complex and are capable of performing advanced calculations that feel very much like programming.

When I talk about coding in Google Sheets, I'm often referring to using Apps Script to create automations—either "fully automated" processes or what I like to call "semi-automations."

Let me explain what I mean by those terms:

Semi-Automations: These are user-initiated automations. For example, you might create a custom menu that appears when the sheet is opened, using the onOpen() function. Or, you might set up something with the onEdit() function, where specific actions are triggered by the user's input or edits. These automations still require some manual interaction, but they streamline the process significantly.
Full Automations: These are fully automated processes triggered without any manual intervention. By writing functions in Apps Script and using time-driven triggers or other installable triggers, you can set these automations to run on their own. For instance, you could have a script that runs every morning to update your data or send an email report—no manual action required.

While "semi-automations" and "full automations" are terms I've coined myself to differentiate between these levels of automation, they help me—and hopefully you—remember that even something automated can still involve a bit of manual effort. And sometimes, that's exactly what people need when they ask for automation.

If you're already familiar with a programming language and are curious about diving into coding specifically within Google Sheets, I have a 15-minute video that covers some fascinating aspects you'll want to know.

Basically, Apps Script unlocks the full potential of Google Sheets, allowing you to turn your spreadsheet into a powerful tool that does exactly what you need.

What is the CODE() Formula in Google Sheets?

The CODE() formula in Google Sheets isn’t about coding—it's a function that converts the first character of a string into its numeric Unicode value. For example, =CODE("A") returns 65, the Unicode value for "A".

This is the reverse of the CHAR() formula, which converts a number into its corresponding character. For instance, =CHAR(65) will give you "A".

Knowing how to use the CODE() function can really boost your Google Sheets skills. It's super helpful for working with text, organizing your data, and comparing information. It’s like a secret tool for more advanced spreadsheet tasks!

Can I Write Python Code in Google Sheets?

While you can't write Python code directly in Google Sheets, there are clever ways to make them work together. Special add-ons let you run Python code right inside your spreadsheet. Plus, Google has tools that allow Python programs to talk to and change your sheets.

This means you can use Python's power to automate tasks, analyze your data, and supercharge your spreadsheets!

Does Google Sheets Have VBA Code?

Unlike Microsoft Excel, which uses VBA, Google Sheets has its own special language called Apps Script. It's based on JavaScript and made just for Google Sheets and other Google tools. So, instead of VBA, you'll be using Apps Script to automate things and create custom features.

What Coding Language Does Google Sheets Use?

Google Sheets uses Apps Script, a variant of JavaScript built just for Google Sheets and other Google tools. With Apps Script it allows you to automate tasks, interact with spreadsheet data, and connect with other Google Workspace apps.

How Do I Write HTML Code in Google Sheets?

While Google Sheets itself doesn't support HTML code directly within its cells, you can use Apps Script to incorporate HTML in various ways. For example, you can create custom dialogs and sidebars with HTML content to enhance your spreadsheets.

To get started, open Google Sheets, go to Extensions > Apps Script, and then use HTML within the HtmlService to design custom interfaces or create interactive elements.

How Do I Code a Cell in Google Sheets?

When it comes to "coding" a cell in Google Sheets, many are referring to using formulas. You can enter formulas by typing an equals sign (=) into a cell, followed by your formula or function.

Google Sheets offers over 500 built-in functions to perform a wide range of tasks. From simple calculations to complex data analysis, there's a function for almost anything. Combine these tools to create powerful formulas and unlock the full potential of your data.

How Do You Code Math in Google Sheets?

Coding math functions in Google Sheets is straightforward and versatile. You can use Google Sheets’ built-in formulas directly within the cells for basic and complex calculations. For instance, you can sum numbers with =SUM(A1:A10), find averages with =AVERAGE(B1:B10), or even perform more intricate operations with combinations of functions.

Google Sheets lets you create custom math functions using Apps Script. Apps Script, based on JavaScript, enables you to create bespoke functions tailored to your needs. Whether you use the built-in tools or create your own, Google Sheets has you covered for all your number crunching needs. Apps Script gives you the flexibility to extend Google Sheets’ capabilities.
