Чтение из документа Word с использованием java

Question

Я пытаюсь прочитать данные из файла docx с помощью java. Данные - это таблицы. Есть ли способ выполнить итерацию через ячейки таблицы и извлечь данные ячейки?

Это должно вам помочь.

Вот код по ссылке:

Answer 2

У вас есть два варианта:

1. Написать библиотеку которые могут открывать, читать и манипулировать документами Word, для некоторых определений «открыть», «прочитать» и «манипулировать», а также некоторое определение «документа Word».

2. Найдите стороннюю библиотеку, которая может выполнить некоторые или все из того, что определено в (1).

Поиск "java docx library" в вашем любимом сетевом поиске и посмотреть, что происходит.
