📊 Data: You have a Google Sheet with sales data for different products and months. The sheet has columns: Product, Month, Sales.

🎯 Deliverable: Create a Google Sheets document and use the Sheets API to add new sales data, update existing sales, and read total sales per product.

Sample Data

Apples	January	120
Bananas	January	150
Apples	February	130
Bananas	February	160

Cherries	February	100

Step 1: Create a new Google Sheet and enter the sample sales data into columns A, B, and C starting from row 1 with headers.

Manually input data or use Sheets UI to create the table as shown in sample_data.

Expected Result

Sheet with columns Product, Month, Sales and 6 rows of data.

2

Step 2: Use the Sheets API to append a new row with sales data: Product='Apples', Month='March', Sales=140.

Use the API method 'spreadsheets.values.append' with range='Sheet1!A:C' and values=[['Apples','March',140]].

Expected Result

New row added at the bottom with Apples, March, 140.

3

Step 3: Use the Sheets API to update the sales for Bananas in February to 170.

Use 'spreadsheets.values.update' with range='Sheet1!C4' and valueInputOption='USER_ENTERED', values=[[170]].

Expected Result

Cell C4 updated from 160 to 170.

4

Step 4: Use the Sheets API to read all sales data and calculate total sales per product.

Use 'spreadsheets.values.get' for range='Sheet1!A2:C' and then sum sales grouped by product in your code or sheet.

Expected Result

Totals: Apples=390, Bananas=320, Cherries=190.

5

Step 5: In the Google Sheet, create a summary table with unique products and total sales using formulas.

In E1 enter 'Product', F1 enter 'Total Sales'. In E2 enter =UNIQUE(A2:A7). In F2 enter =SUMIF(A:A,E2,C:C) and drag down.

Expected Result

Summary table showing Apples 390, Bananas 320, Cherries 190.

Final Result

Product   Month    Sales
Apples   January   120
Bananas  January   150
Apples   February  130
Bananas  February  170
Cherries January   90
Cherries February  100
Apples   March     140

Summary:
Product   Total Sales
Apples    390
Bananas   320
Cherries  190
