Tips for Uploading Excel Files

Ensure your Excel file is saved in a supported format.
Check that the file is not corrupted.
If using the "Lucky Upload" button, the system will auto-select the first sheet for you.

Behind the Scenes

Once you upload a file, our Django backend handles the file safely using the request.FILES object. The file is then read using openpyxl or similar libraries to generate a preview table, preserving cell merges, fonts, and formatting.

JavaScript Enhancements

We use JavaScript to validate the file before submission and to show notifications if no file is selected:


document.getElementById("uploadForm").addEventListener("submit", function(e) {
  const fileInput = document.getElementById("excel_file");
  if (!fileInput.value) {
    e.preventDefault();
    alert("Please select an Excel file before uploading.");
  }
});

This upload page combines a simple user-friendly interface with robust backend handling, ensuring your Excel files are processed efficiently. You can now upload your Excel sheets confidently and preview them before printing or further editing.
