By following these steps, you have successfully set up a Google Cloud Platform project, enabled the Google Sheets API, and created a service account for authentication. You can now use the Google Sheets API to perform CRUD operations on your Google Sheets.

Authenticating and Linking Google Sheets

To perform CRUD operations, you need to authenticate and link your Google Sheets with your JavaScript application. In this section, we will guide you through the process of sharing your Google Sheet with the service account and handling authentication in code.

Sharing the Google Sheet

To share your Google Sheet with the service account, follow these steps:

1. Open your Google Sheet and click on the Share button in the top-right corner.
2. Enter the email address of the service account you created in the previous section.
3. Select the Editor permission to allow the service account to read and write data to your sheet.
4. Click Share to share the sheet with the service account.

Important: Make sure to share the sheet with the correct service account email address to avoid authentication issues.

Handling Authentication in Code

To authenticate your JavaScript application using the service account, you will need to use the downloaded JSON file with service account credentials. Here's an example of how to do it:

const { google } = require('googleapis');
const auth = new google.auth.GoogleAuth({
  keyFile: 'path/to/service-account-credentials.json',
  scopes: ['https://www.googleapis.com/auth/spreadsheets'],
});

In this example, we are using the google-auth-library to create a new instance of GoogleAuth with the service account credentials and scopes. The keyFile property is set to the path of the JSON file containing the service account credentials, and the scopes property is set to the scope required for accessing the Google Sheets API.

By following these steps, you have successfully authenticated and linked your Google Sheets with your JavaScript application. You can now use the Google Sheets API to perform CRUD operations on your sheets.

Security Reminder: Store the private key file securely and do not share it with anyone to avoid security risks.

Performing CRUD Operations

Reading Data from Sheets

To read data from a Google Sheet using the Sheets API, you need to specify the spreadsheet ID, range, and other parameters in your API request. Here's an example:

const spreadsheetId = 'your-spreadsheet-id';
const range = 'Sheet1!A1:B2'; // Specify the range of cells to read

const request = {
  spreadsheetId,
  range,
};

const response = await google.sheets('v4').spreadsheets.values.get(request);
const values = response.data.values;

// Process the retrieved data
console.log(values);

What's happening:

• We're using the google.sheets('v4').spreadsheets.values.get() method to retrieve data from the specified range.
• The response.data.values property contains the retrieved data, which you can then process and use in your application.

Adding New Data to Sheets

To add new data to a Google Sheet, you can use the google.sheets('v4').spreadsheets.values.update() method. Here's an example:

const spreadsheetId = 'your-spreadsheet-id';
const range = 'Sheet1!A1:B2'; // Specify the range of cells to update
const values = [
  ['New data 1', 'New data 2'],
  ['New data 3', 'New data 4'],
];

const request = {
  spreadsheetId,
  range,
  valueInputOption: 'USER_ENTERED',
  resource: { values },
};

const response = await google.sheets('v4').spreadsheets.values.update(request);
console.log(response);

What's happening:

• We're using the google.sheets('v4').spreadsheets.values.update() method to add new data to the specified range.
• The valueInputOption property is set to USER_ENTERED to specify that the values should be treated as user-input data.

Modifying Existing Data

To modify existing data in a Google Sheet, you can use the google.sheets('v4').spreadsheets.values.update() method with the valueInputOption property set to USER_ENTERED. Here's an example:

const spreadsheetId = 'your-spreadsheet-id';
const range = 'Sheet1!A1:B2'; // Specify the range of cells to update
const values = [
  ['Updated data 1', 'Updated data 2'],
  ['Updated data 3', 'Updated data 4'],
];

const request = {
  spreadsheetId,
  range,
  valueInputOption: 'USER_ENTERED',
  resource: { values },
};

const response = await google.sheets('v4').spreadsheets.values.update(request);
console.log(response);

What's happening:

• We're using the google.sheets('v4').spreadsheets.values.update() method to modify existing data in the specified range.
• The valueInputOption property is set to USER_ENTERED to specify that the values should be treated as user-input data.

Removing Data from Sheets

To remove data from a Google Sheet, you can use the google.sheets('v4').spreadsheets.values.clear() method. Here's an example:

const spreadsheetId = 'your-spreadsheet-id';
const range = 'Sheet1!A1:B2'; // Specify the range of cells to clear

const request = {
  spreadsheetId,
  range,
};

const response = await google.sheets('v4').spreadsheets.values.clear(request);
console.log(response);

What's happening:

• We're using the google.sheets('v4').spreadsheets.values.clear() method to remove data from the specified range.

By following these examples, you can perform CRUD operations on your Google Sheets data using the Sheets API and JavaScript.
