Tutorial: Learn to Work with Excel Worksheets using Aspose.Cells Cloud API

Introduction

Welcome to this comprehensive tutorial on working with Excel worksheets using Aspose.Cells Cloud API. In this tutorial, you’ll learn how to perform essential worksheet operations programmatically, including creating, modifying, and managing worksheets within Excel workbooks.

Prerequisites

Before starting this tutorial, make sure you have:

  1. An Aspose Cloud account (sign up for a free trial if you don’t have one)
  2. Your Client ID and Client Secret from the Aspose Cloud dashboard
  3. Basic knowledge of REST APIs and HTTP concepts
  4. Familiarity with your programming language of choice (we’ll provide examples in multiple languages)
  5. A development environment or API testing tool (like Postman, cURL, etc.)

Tutorial Steps

Step 1: Authentication with Aspose.Cells Cloud API

Before working with worksheets, you need to authenticate with the Aspose.Cells Cloud API. This requires obtaining an access token using your Client ID and Client Secret.

Try it yourself:

curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

The response will include an access token that you’ll use in subsequent API calls:

{
  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expires_in": 3600,
  "token_type": "Bearer"
}

Step 2: Get All Worksheets in a Workbook

Let’s start by retrieving information about all worksheets in an existing Excel workbook.

curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets" \
-X GET \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

This API returns information about all worksheets in the specified workbook, including their names and properties.

Example Response:

{
  "Worksheets": {
    "WorksheetList": [
      {
        "link": {
          "Href": "/Sheet1",
          "Rel": "self"
        }
      },
      {
        "link": {
          "Href": "/Sheet2",
          "Rel": "self"
        }
      }
    ],
    "link": {
      "Href": "http://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets",
      "Rel": "self"
    }
  },
  "Code": "200",
  "Status": "OK"
}

SDK Example (Python):

# Get All Worksheets Example
import requests
import json

# Authentication
auth_url = "https://api.aspose.cloud/connect/token"
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"

auth_data = {
    "grant_type": "client_credentials",
    "client_id": client_id,
    "client_secret": client_secret
}

auth_headers = {
    "Content-Type": "application/x-www-form-urlencoded",
    "Accept": "application/json"
}

auth_response = requests.post(auth_url, data=auth_data, headers=auth_headers)
access_token = auth_response.json().get("access_token")

# Get all worksheets
api_url = "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets"
headers = {
    "Content-Type": "application/json",
    "Accept": "application/json",
    "Authorization": f"Bearer {access_token}"
}

response = requests.get(api_url, headers=headers)
print(json.dumps(response.json(), indent=2))

# Output worksheet names
if response.status_code == 200:
    worksheets = response.json().get("Worksheets", {}).get("WorksheetList", [])
    print("\nWorksheets in the workbook:")
    for idx, worksheet in enumerate(worksheets, 1):
        sheet_name = worksheet.get("link", {}).get("Href", "").strip("/")
        print(f"{idx}. {sheet_name}")

Step 3: Create a New Worksheet

Now let’s learn how to create a new worksheet in an existing workbook.

curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/NewSheet" \
-X PUT \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

In this example, we’re creating a new worksheet named “NewSheet”. You can also specify the position of the new worksheet using query parameters.

SDK Example (C#):

// Add a new worksheet example
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace AsposeCellsTutorials
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // Authentication
            var client = new HttpClient();
            var authRequest = new HttpRequestMessage(HttpMethod.Post, "https://api.aspose.cloud/connect/token");
            
            var authContent = new FormUrlEncodedContent(new Dictionary<string, string>
            {
                {"grant_type", "client_credentials"},
                {"client_id", "YOUR_CLIENT_ID"},
                {"client_secret", "YOUR_CLIENT_SECRET"}
            });
            
            authRequest.Content = authContent;
            var authResponse = await client.SendAsync(authRequest);
            var authResult = await authResponse.Content.ReadAsStringAsync();
            
            // Parse access token from JSON response
            // For simplicity, using basic string operations
            var accessToken = authResult.Split("\"access_token\":\"")[1].Split("\"")[0];
            
            // Add new worksheet
            var apiClient = new HttpClient();
            apiClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
            
            var apiUrl = "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/NewSheet";
            var response = await apiClient.PutAsync(apiUrl, null);
            
            if (response.IsSuccessStatusCode)
            {
                Console.WriteLine("Worksheet 'NewSheet' created successfully!");
            }
            else
            {
                Console.WriteLine($"Error: {response.StatusCode} - {await response.Content.ReadAsStringAsync()}");
            }
        }
    }
}

Step 4: Copy a Worksheet

Copying worksheets is a common operation, and Aspose.Cells Cloud API makes it simple:

curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/copy" \
-X POST \
-d "{ \"SourceSheet\": \"Sheet1\", \"DestinationSheet\": \"CopiedSheet\" }" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

This example copies the content of “Sheet1” to a new worksheet named “CopiedSheet”.

SDK Example (Java):

// Copy worksheet example
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.util.Base64;
import java.util.Scanner;

public class CopyWorksheetExample {
    public static void main(String[] args) {
        try {
            // Authentication
            String clientId = "YOUR_CLIENT_ID";
            String clientSecret = "YOUR_CLIENT_SECRET";
            String authUrl = "https://api.aspose.cloud/connect/token";
            
            URL url = new URL(authUrl);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            conn.setRequestProperty("Accept", "application/json");
            conn.setDoOutput(true);
            
            String authData = "grant_type=client_credentials&client_id=" + clientId + "&client_secret=" + clientSecret;
            try (OutputStream os = conn.getOutputStream()) {
                byte[] input = authData.getBytes(StandardCharsets.UTF_8);
                os.write(input, 0, input.length);
            }
            
            // Read auth response
            Scanner scanner = new Scanner(conn.getInputStream());
            String authResponse = scanner.useDelimiter("\\A").next();
            scanner.close();
            
            // Extract access token (simple approach for demonstration)
            String accessToken = authResponse.split("\"access_token\":\"")[1].split("\"")[0];
            
            // Copy worksheet
            String apiUrl = "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/copy";
            URL copyUrl = new URL(apiUrl);
            HttpURLConnection copyConn = (HttpURLConnection) copyUrl.openConnection();
            copyConn.setRequestMethod("POST");
            copyConn.setRequestProperty("Content-Type", "application/json");
            copyConn.setRequestProperty("Accept", "application/json");
            copyConn.setRequestProperty("Authorization", "Bearer " + accessToken);
            copyConn.setDoOutput(true);
            
            String copyData = "{ \"SourceSheet\": \"Sheet1\", \"DestinationSheet\": \"CopiedSheet\" }";
            try (OutputStream os = copyConn.getOutputStream()) {
                byte[] input = copyData.getBytes(StandardCharsets.UTF_8);
                os.write(input, 0, input.length);
            }
            
            int responseCode = copyConn.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                System.out.println("Worksheet copied successfully!");
            } else {
                System.out.println("Error: " + responseCode);
                Scanner errorScanner = new Scanner(copyConn.getErrorStream());
                System.out.println(errorScanner.useDelimiter("\\A").next());
                errorScanner.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Step 5: Rename a Worksheet

Renaming worksheets is another important operation. Here’s how to do it:

curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/rename?newname=RenamedSheet" \
-X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

This example renames “Sheet1” to “RenamedSheet”.

Step 6: Change Worksheet Visibility

You can hide or unhide worksheets as needed:

# Hide a worksheet
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/visible?isVisible=false" \
-X PUT \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Unhide a worksheet
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/visible?isVisible=true" \
-X PUT \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

Step 7: Delete a Worksheet

When a worksheet is no longer needed, you can delete it:

curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet2" \
-X DELETE \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

This example deletes “Sheet2” from the workbook.

Step 8: Export a Worksheet to Different Formats

Aspose.Cells Cloud API allows you to export worksheets to various formats, including PDF, image formats, and more:

# Export worksheet to PNG
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1?format=png" \
-X GET \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
--output worksheet.png

# Export worksheet to PDF
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1?format=pdf" \
-X GET \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
--output worksheet.pdf

Step 9: AutoFitting Rows and Columns

Optimize the display of your worksheets by autofitting rows and columns:

# Autofit a column
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/autofitcolumns?firstColumn=0&lastColumn=5" \
-X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Autofit a row
curl -v "https://api.aspose.cloud/v3.0/cells/myWorkbook.xlsx/worksheets/Sheet1/autofitrows?startRow=0&endRow=10" \
-X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

What You’ve Learned

In this tutorial, you’ve learned how to:

  • Authenticate with Aspose.Cells Cloud API
  • Retrieve information about worksheets in a workbook
  • Create, copy, rename, and delete worksheets
  • Manage worksheet visibility
  • Export worksheets to different formats
  • Optimize worksheet display with autofitting

Troubleshooting Tips

  • Authentication Issues: Make sure your Client ID and Client Secret are correct. The access token expires after one hour, so you may need to request a new one.
  • File Not Found Errors: Ensure that the workbook you’re trying to access exists in the specified location. If you’re using a custom storage, make sure it’s properly configured.
  • Invalid JSON: When sending JSON in the request body, ensure it’s properly formatted.
  • API Rate Limiting: If you receive 429 (Too Many Requests) responses, you might have exceeded your API quota. Consider upgrading your plan or optimizing your API usage.

Further Practice

To reinforce your learning, try these exercises:

  1. Create a workbook with multiple worksheets, each with different formatting
  2. Copy data between worksheets
  3. Implement a batch operation to rename multiple worksheets
  4. Export worksheets to various formats and compare the results
  5. Create a script that backs up all worksheets in a workbook as separate files
