Đọc file excel trong scala

Trước đó chúng tôi đã giới thiệu Apache POI- một API Java hữu ích để tương tác với các tài liệu Microsoft Office. Bây giờ chúng ta sẽ xem làm thế nào chúng ta có thể đọc và ghi vào tệp excel bằng API

Thủ tục. Viết tệp bằng POI rất đơn giản và bao gồm các bước sau

  1. Tạo sổ làm việc
  2. Tạo sheet trong workbook
  3. Tạo một hàng trong trang tính
  4. Thêm ô trong trang tính
  5. Lặp lại bước 3 và 4 để ghi thêm dữ liệu
  6. Đóng luồng đầu ra

Thí dụ

Đọc một tệp Excel

Thủ tục. Việc đọc một file excel cũng rất đơn giản nếu chúng ta chia thành các bước

  1. Tạo phiên bản sổ làm việc từ trang tính excel
  2. Đến trang tính mong muốn
  3. Tăng số hàng
  4. lặp lại trên tất cả các ô trong một hàng
  5. lặp lại bước 3 và 4 cho đến khi tất cả dữ liệu được đọc
  6. Đóng luồng đầu ra
