Google Spreadsheet Script Examples for Beginners

Google Spreadsheets is an incredibly powerful tool, but it's even more impressive when you unlock its full potential with scripts. A script is a set of instructions that automates tasks and makes your spreadsheet do more than just basic calculations.

By using Google Spreadsheet scripts, you can create custom functions, automate repetitive tasks, and even integrate your spreadsheet with other Google apps. The possibilities are endless, and it's amazing how much you can achieve with just a few lines of code.

One of the best things about Google Spreadsheet scripts is that they're incredibly easy to learn, even for beginners. With a little practice, you can create your own custom scripts and start automating tasks in no time.

To get started with Google Apps Script, all you need is a Google account, a browser, and an internet connection.

You can create a new spreadsheet in Google Drive and give it a name, like "My First Script".

To open the Apps Script editor, click Extensions > Apps Script from the menu, or Tools > Script editor if you can't find the Extensions menu.

The Apps Script editor will launch in a separate tab in your browser.

To write your first code, you'll need to create a function, like the writeHelloWorld() function that writes "Hello world!" to the spreadsheet.

This function uses the SpreadsheetApp class to get an object representing the active sheet using the getActiveSheet() method.

Classes in Google Apps Script are templates that encapsulate data with code for creating objects. They're specific to Google implementations, so don't worry if you're thinking, "But JavaScript is class-free!".

Google Apps Script provides several top-level classes, which allow you to access features of other Google apps and services. These classes are the foundation of what you can do with Apps Script.

Some examples of top-level classes include SpreadsheetApp, DocumentApp, DriveApp, GmailApp, and LanguageApp. These classes let you interact with Google Sheets, Google Docs, Google Drive, Gmail, and the language service.

You can access user info and control script logs and dialog boxes using base classes. These include the Browser class, which provides access to dialog boxes specific to Google Sheets, and the Logger class, which allows you to write out values to the execution logs.

Here are some examples of base classes:

The V8 runtime for Apps Script also supports classes, which lets you create your own classes. This is a powerful feature that allows you to organize your code with inheritance, kind of like creating a blueprint from which copies can be made.

Data Management is a crucial aspect of working with Google Spreadsheets. You can load data from a Google account and schedule a refresh, making it easy to keep your data up-to-date.

For another approach, see: Google Data Studio Examples

To load data, you can select a spreadsheet and the sheet where the data will be loaded, or type in a name to create a new sheet. You can also specify the target cell or range where your data will be imported, either by overwriting all data to the right or inserting data into a defined range.

Import mode options include Replace, which substitutes all previously imported information with the latest data, and Append, which adds new data below the previously imported entries. You can also enable Last updated column to add a column showing the date and time of the last data refresh.

Here are some import options to consider:

Data validation is a crucial aspect of data management. Apps Script lets you access existing data-validation rules in Google Sheets or create new rules.

You can set a data-validation rule that allows only numbers between 1 and 100 on a cell. This is done using SpreadsheetApp.newDataValidation().

Data validation rules can be complex, but Apps Script makes it easy to create custom rules. For instance, you can use DataValidationBuilder to create a rule that meets your specific needs.

To apply a data-validation rule to a cell, you can use Range.setDataValidation(rule). This is a straightforward process that ensures data accuracy and consistency.

Importing data from CSV files via the web can be a convenient and efficient way to manage your data.

You can write your own function using Google Apps Script (GAS) to import a CSV file from a URL and choose only a few columns to import. This can be done by coding a custom function, such as the CUSTOMCSVIMPORT function, which allows you to specify the columns to import.

One alternative to coding your own function is to use a built-in import mode option in your data management tool. This option allows you to specify the target cell or range where your data will be imported, such as overwriting all data to the right or inserting data into a defined range.

You can choose between two import mode options: Replace and Append. Replace is suitable if you want to substitute all previously imported information with the latest data from the source, while Append adds new data below the previously imported entries.

If you want to track historical data changes, you can enable the Last updated column option, which adds a column showing the date and time of the last data refresh. This can be useful for keeping track of when your data was last updated.

Here are the import mode options and how they work:

Custom functions can be a game-changer for simplifying complex spreadsheet tasks. They can replace numerous built-in Sheets functions, reducing complexity and making data management more efficient.

To summarize data from multiple sheets, you can use a custom function that iterates through sheets in a spreadsheet to perform custom calculations. This allows you to create a summary of each sheet.

You can also exclude specific sheets from your calculations if needed. This feature is especially useful when you have a lot of data and want to focus on specific sheets.

Processing spreadsheet data using optimized array objects can also be done with this custom function. This helps to improve performance and make data management faster.

Here are some key benefits of summarizing data with custom functions:

You can efficiently clean up data in a spreadsheet using Editor Add-ons, which are highly customizable and can automate common tasks in Google Sheets.

Editor Add-ons can automatically remove empty rows and columns, cropping the spreadsheet to the edges of the data range.

To identify and delete empty rows and columns, use arrays, which can efficiently pinpoint the empty cells.

You can fill in data gaps without overwriting non-empty cells, making it easier to work with your data.

With Editor Add-ons, you can build a custom menu that displays under the Extensions menu in Sheets, giving you easy access to your cleaning tools.

Here are some ways Editor Add-ons can help you clean up your data:

Connecting to Google Forms is a powerful feature in Apps Script that allows you to automate tasks between your forms and spreadsheets. You can create a Google Form based on data in a spreadsheet with Forms and Spreadsheet services.

You can embed charts in a Google Spreadsheet using Apps Script to represent data in a specific range.

Apps Script lets you create interactive and dynamic charts that can be easily customized.

To generate an embedded bar chart, you'll need to have chartable data in cells A1:B15.

Embedded charts can be used to visualize data and make it easier to understand.

To learn more about embedding a chart into your spreadsheet, see EmbeddedChart and specific chart builders, such as EmbeddedPieChartBuilder.

A custom function in Google Sheets is similar to a built-in spreadsheet function, but you define its behavior with Apps Script. You can create a custom function like in2mm() that converts a value from inches to millimeters.

Macros are another way to execute Apps Script code from Google Sheets, and you can activate them with a keyboard shortcut or through the Google Sheets menu.

To create custom functions and macros, you can use the Apps Script editor, which allows you to rename your project, add a new function, and save your changes.

To use the Google Apps Script Editor, you can rename your project, which is a great way to keep your work organized.

You can add a new function to your script, which is a block of code that performs a specific task.

To save your changes, you can use the built-in save feature of the Apps Script editor.

Writing data to a spreadsheet is a straightforward process. You can do this by adding a specific code to the end of your script.

The code appends a new row at the bottom of the spreadsheet, with the values specified. If you run this function, you'll see a new row added to the spreadsheet.

You can specify the values to be added in the code, such as a new product name and number. This makes it easy to update your spreadsheet with new information.

Here are the ways to specify the target cell or range where your data will be imported:

This allows you to choose how your data is imported, whether you need to perform calculations or insert data without erasing existing information.

Custom functions in Google Sheets are a powerful tool that allows you to define your own functions with Apps Script. You can create a custom function, like in2mm(), that converts a value from inches to millimeters.

These custom functions can be used in your spreadsheet just like built-in functions, by typing the function name followed by the value you want to convert. For example, =in2mm(A1) or =in2mm(10) into a cell.

Custom functions can also reduce spreadsheet complexity by replacing numerous built-in Sheets functions. They can be particularly useful when you have similarly structured data on multiple sheets in a spreadsheet.

Here are some benefits of using custom functions:

Macros are another way of executing Apps Script code from the Google Sheets UI. Unlike custom functions, you activate them with a keyboard shortcut or through the Google Sheets menu.

You can create custom functions in Google Sheets using Google Apps Script. These functions can be used to perform calculations that aren't available through built-in functions.

For example, you can create a function to convert Fahrenheit to Celsius, which is exactly what one example shows. This function takes a single numeric argument, the temperature in Fahrenheit, and returns the temperature in Celsius.

Google Apps Script also allows you to create custom numeric functions that can be used in your spreadsheet. One example is the AREAOFCIRCLE function, which calculates the area of a circle given the radius.

To use a custom function, you simply type an equals sign followed by the function name and any input value. For instance, if you have the radius of a circle in cell A2, you can type =AREAOFCIRCLE(A2) and press Enter.

Custom functions can also include error handling, so if you try to use a function with an invalid input, you'll get an error message. This is shown in the example where the function returns an error message for a non-numeric value.
