Let’s fix that by adding a custom menu to the menu bar of our spreadsheet so a user can run the script within the spreadsheet without needing to open up the editor window.
In its current form, our program is pretty useless for many reasons, not least because we can only run it from the script editor window and not from our spreadsheet. Adding a custom menu in Google Apps Script Hence, we name our function helloWorld, with a lowercase h at the start of hello and an uppercase W at the start of World. Note, it’s convention in Apps Script to use the CamelCase naming convention, starting with a lowercase letter. This isn’t very descriptive, so let’s rename it to helloWorld(), which gives us some context. run it to do something) I would write myFunction(). Every time I want to call this function (i.e. We should rename our function to something more meaningful.Īt present, it’s called myFunction which is the default, generic name generated by Google. Great job! You’ve now written your first apps script program. Return to your Google Sheet and you should see the output of your program, a message box popup with the classic “Hello world!” message: If anything goes wrong with your code, this is the stage when you’d see a warning message (instead of the yellow message, you’ll get a red box with an error message in it). Once you’ve authorized the Google App script, the function will run (or execute). More information can be found in this detailed blog post from Google Developer Expert Martin Hawksey. Then type in the words “Continue” on the next screen, click Next, and finally review the permissions and click “ALLOW”, as shown in this image (showing a different script in the old editor):

Furthermore, the apps script projects in this post are not intended to be published publicly for other users, so we don’t need to submit it to Google for review (although if you want to do that, here’s more information).Ĭlick the “Advanced” button in the bottom left of the review permissions pop-up, and then click the “Go to Starter Script Code (unsafe)” at the bottom of the next screen to continue. In our case, since we are the creator of the app, we know it’s safe so we do want to continue. ❗️When your first run your apps script, you may see the “app isn’t verified” screen and warnings about whether you want to continue. In this instance the app wants to view and manage your spreadsheets in Google Drive, so click Allow (otherwise your script won’t be able to interact with your spreadsheet or do anything): When you hit the run button for the first time, you will be prompted to authorize the app to run:Ĭlicking Review Permissions pops up another window in turn, showing what permissions your app needs to run.
Google Scripts have robust security protections to reduce risk from unverified apps, so we go through the authorization workflow when we first authorize our own apps. Your code window should now look like this:
In the code window, between the curly braces after the function myFunction() syntax, write the following line of code so you have this in your code window: This will open a new tab in your browser, which is the Google Apps Script editor window:īy default, it’ll open with a single Google Script file ( code.gs) and a default code block, myFunction(): Then click the menu: Extensions > Apps Script Let’s write our first, extremely basic program, the classic “Hello world” program beloved of computer teaching departments the world over.
