Google Apps Script: Copy Sheet To New Spreadsheet

Hey guys! Today, we're diving into the wonderful world of Google Apps Script to learn how to copy a sheet from one spreadsheet to a brand new one. This is super useful when you want to create backups, generate reports, or even build templates. So, let's get started!

Setting Up Your Google Sheet

First things first, you'll need a Google Sheet to work with. If you already have one, great! If not, head over to Google Sheets and create a new one. Populate it with some data – it doesn't matter what, just something to make the sheet interesting. This way, when we copy it, you'll see the magic happen in real-time. Make sure the sheet you want to copy is properly named; this will help us identify it easily in the script.

Give your sheet a name like "OriginalData" or something similar. The key is to keep it straightforward so you know exactly which sheet you're targeting. Once you've got your data and your sheet is named, we can jump into the Apps Script editor. To do this, go to "Tools" in the menu and select "Script editor". This opens a new tab where we'll write our JavaScript code to copy the sheet.

The Apps Script editor is where the real fun begins. It's a cloud-based IDE (Integrated Development Environment) that lets you write and run code directly connected to your Google Sheets, Docs, Forms, and more. You can think of it as your coding playground specifically designed for Google Workspace apps. Once the script editor is open, you'll see a blank canvas ready for your code. We'll walk through the code step-by-step, explaining each part so you understand what's happening under the hood. Remember, the goal is not just to copy and paste the code, but to truly understand it so you can adapt it for your own unique needs. So, buckle up and let's get coding!

Writing the Google Apps Script

Okay, now for the main event: writing the Google Apps Script that copies our sheet. I'll break it down into manageable chunks, explaining each part as we go. Copy and paste this code into your script editor:

function copySheetToNewSpreadsheet() {
  // Get the source spreadsheet
  var sourceSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();

  // Get the sheet you want to copy
  var sheetToCopy = sourceSpreadsheet.getSheetByName("OriginalData"); // Replace with your sheet name

  // Create a new spreadsheet
  var newSpreadsheet = SpreadsheetApp.create("Copied Spreadsheet");

  // Copy the sheet to the new spreadsheet
  sheetToCopy.copyTo(newSpreadsheet);

  // Log the URL of the new spreadsheet (optional)
  Logger.log("New spreadsheet URL: " + newSpreadsheet.getUrl());
}

Let's break down this script step by step:

  1. function copySheetToNewSpreadsheet() {: This line defines our function. Everything inside these curly braces {} will be executed when we run the function.
  2. var sourceSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();: This line gets the current spreadsheet you're working in. SpreadsheetApp is a built-in object that provides access to the Google Sheets application, and getActiveSpreadsheet() returns the spreadsheet that's currently open.
  3. var sheetToCopy = sourceSpreadsheet.getSheetByName("OriginalData");: This is where you specify which sheet you want to copy. Replace "OriginalData" with the actual name of your sheet. getSheetByName() retrieves the sheet with the specified name from the source spreadsheet.
  4. var newSpreadsheet = SpreadsheetApp.create("Copied Spreadsheet");: This line creates a brand new spreadsheet. The create() method takes a string as an argument, which becomes the name of the new spreadsheet.
  5. sheetToCopy.copyTo(newSpreadsheet);: This is the line that does the actual copying! copyTo() is a method of the Sheet object, and it copies the sheet to the specified spreadsheet.
  6. Logger.log("New spreadsheet URL: " + newSpreadsheet.getUrl());: This line is optional, but it's super helpful. It logs the URL of the new spreadsheet to the Apps Script execution log. You can view the log by going to "View" > "Logs" in the script editor.

Running the Script

Alright, now that we've got our script written, it's time to run it! Here’s how:

  1. Save Your Script: Click the save icon (it looks like a floppy disk) in the script editor. Give your script a name, like "CopySheet".
  2. Select the Function: In the script editor, you'll see a dropdown menu labeled "Select function". Choose copySheetToNewSpreadsheet from the list.
  3. Run the Function: Click the "Run" button (it looks like a play button) next to the dropdown menu. The first time you run the script, Google will ask you to authorize it. This is because the script needs permission to access your Google Sheets and create new spreadsheets. Click "Review Permissions" and follow the prompts to grant the necessary permissions. Choose your Google account and then, you might see a warning that says, "This app isn't verified".

Don't worry! This just means that you're the only one using this script, so Google hasn't verified it. Click "Advanced" and then "Go to CopySheet (unsafe)". Finally, click "Allow" to grant the script the permissions it needs.

Once you've authorized the script, run it again. This time, you should see the script execute without any errors. Check your Google Drive, and you should find a new spreadsheet named "Copied Spreadsheet" (or whatever name you gave it). Open it up, and you'll see that it contains a perfect copy of your original sheet!

If you encounter any errors, double-check your code for typos and make sure you've replaced `
