Your browser does not support viewing this file. Please download the file to view it.
Replace path/to/yourfile.xlsx with the actual path to your Excel file.
Ensure the type attribute matches the file’s MIME type.
🔍 Note: The file must be accessible from the web server where your JSP pages are hosted.
Method 2: Using JExcel API For a more programmatic approach, you can use the JExcel API to read and display Excel content dynamically:
import jxl.;
import java.io. ;
// Steps to display data from Excel
Workbook workbook = Workbook.getWorkbook(new File(“path/to/yourfile.xls”));
Sheet sheet = workbook.getSheet(0);
for (int i = 0; i < sheet.getRows(); i++) {
for (int j = 0; j < sheet.getColumns(); j++) {
Cell cell = sheet.getCell(j, i);
// Display cell content here
}
}
Include the JExcel API in your project’s classpath.
Handle file access permissions and ensure the file is accessible.
⚙️ Note: JExcel API has limitations with newer Excel formats; consider using libraries like Apache POI for broader compatibility.
Method 3: Using Apache POI Apache POI provides extensive functionality for handling Excel files in Java. Here’s how you can read and display an Excel document:
import org.apache.poi.ss.usermodel.;
import org.apache.poi.xssf.usermodel. ;
import java.io.FileInputStream;
import java.io.FileOutputStream;
FileInputStream file = new FileInputStream(new File(“path/to/yourfile.xlsx”));
Workbook workbook = new XSSFWorkbook(file);
Sheet sheet = workbook.getSheetAt(0);
for (Row row : sheet) {
for (Cell cell : row) {
// Display cell content here
}
}
file.close();
Add Apache POI dependencies to your project.
Handle resource management to avoid memory leaks.
Method 4: Embedding Excel in an iFrame An alternative way to display Excel documents is by embedding them within an
Adjust the width and height attributes to fit your design.
Ensure cross-origin resource sharing (CORS) policies are managed if necessary.
Method 5: Using Google Sheets API Leveraging Google Sheets to handle Excel files can provide cloud-based solutions for embedding:
Enable Google Sheets API in Google Cloud Console and set up OAuth 2.0 credentials.
Authorize your app to access the Google Sheets API.
Use Google Sheets API to read data from your Excel file:
// Java code to interact with Google Sheets
ServiceAccountCredentials credentials = ServiceAccountCredentials.fromStream(new FileInputStream(“credentials.json”));
Sheets service = new Sheets.Builder(httpTransport, JSON_FACTORY, credentials).build();
Sheets.Spreadsheets.Values.Get request = service.spreadsheets().values().get(“spreadsheetId”, “range”);
ValueRange response = request.execute();
List> values = response.getValues();
// Loop through and display the values
Embedding Excel sheets in JSP pages can greatly enhance the user experience by allowing direct data access and manipulation. This integration can range from simple file embedding to complex data processing with APIs. Here are some final thoughts:
