Creating Excel files on Android can be a useful feature for applications that deal with data management or need to generate reports. In this tutorial, we will explore the steps to create an Excel file programmatically using Android Studio.
Step 1: Set up Android Studio and create a new project.
Before we begin, make sure that you have the latest version of Android Studio installed and set up on your computer. Once you’re ready, create a new Android project by following these steps:
1. Open Android Studio.
2. Click on "Start a new Android Studio project" or select "File" > "New" > "New Project."
3. Follow the prompts to set up your project, including choosing a project name and target devices.
Step 2: Add the necessary dependencies.
To create Excel files programmatically, we’ll need an external library. In this tutorial, we will use Apache POI, a popular Java library for manipulating Office documents. To add the Apache POI dependencies to your Android project, do the following:
1. Open the build.gradle file for your app module.
2. Inside the dependencies block, add the following lines:
"`groovy
implementation ‘org.apache.poi:poi:5.0.0’
implementation ‘org.apache.poi:poi-ooxml:5.0.0’
"`
Step 3: Write the code to create an Excel file.
Now that we have the necessary dependencies, we can start writing the code to create an Excel file. Here’s an example code snippet to get you started:
"`java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
…
// Create a new Excel workbook
Workbook workbook = new XSSFWorkbook();
// Create a new sheet
Sheet sheet = workbook.createSheet("My Sheet");
// Create a new row
Row row = sheet.createRow(0);
// Create cells with data
Cell cell1 = row.createCell(0);
cell1.setCellValue("Hello");
Cell cell2 = row.createCell(1);
cell2.setCellValue("World");
…
// Save the workbook to a file
String filePath = "path/to/your/file.xlsx";
FileOutputStream fileOut = new FileOutputStream(filePath);
workbook.write(fileOut);
fileOut.close();
workbook.close();
"`
Step 4: Run the application and check the Excel file.
After writing the code, run your application on an emulator or a physical device. Once the application is launched, the code will create an Excel file with the specified data. You can then check the output file in the specified file path to see the created Excel file.
Step 5: Customize and enhance the Excel file creation.
The code snippet provided is a basic example to get you started with creating an Excel file on Android. You can further customize and enhance the creation process by exploring the Apache POI documentation and its various APIs. This will allow you to add more complex functionality, formatting options, and data manipulation capabilities to your Excel files.

How to open Excel file in android studio programmatically?
Opening an Excel file programmatically in Android Studio can be achieved by following a few steps. Here’s how you can do it:
1. Add the necessary permissions: Open your AndroidManifest.xml file and add the following permissions:
"`xml
"`
These permissions are required to read and write files on the device’s storage.
2. Check if the device has an Excel viewer app: Before opening the Excel file, it’s a good practice to check if the device has an app capable of opening it. You can use the PackageManager to check for an Excel viewer package:
"`java
boolean hasExcelViewer = false;
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("application/vnd.ms-excel");
List
if (resolveInfoList.size() > 0) {
hasExcelViewer = true;
}
"`
If `hasExcelViewer` is `true`, it means an Excel viewer app is available on the device.
3. Open the Excel file using an Intent: If a viewer app is available, you can create an Intent to open the Excel file. Here’s how you can do it:
"`java
File file = new File(filePath); // Specify the path of the Excel file
Uri fileUri = FileProvider.getUriForFile(this, "com.yourpackage.fileprovider", file); // Generate a content URI using FileProvider
Intent excelIntent = new Intent(Intent.ACTION_VIEW);
excelIntent.setDataAndType(fileUri, "application/vnd.ms-excel");
excelIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
List
if (excelResolveInfoList.size() > 0) {
startActivity(excelIntent);
} else {
// Display a message to the user indicating that no Excel viewer app is installed
}
"`
Make sure to replace `"com.yourpackage.fileprovider"` with the authority value you have defined for the FileProvider in your app’s manifest.
By following these steps, you should be able to open Excel files programmatically in your Android Studio project. Remember to handle exceptions properly and provide appropriate error handling in case the necessary permissions are not granted or an Excel viewer app is not available on the device.
