You can fetch the tables, the paragraphs etc, then remove them, add new ones, change the text of them etc. It's all the same process then as editing the main document. Since your document is in .docx

I am working on a simple task: Reading an Excel file and converting it to an object. Though, I am facing a problem in reading the Excel file (.xls) I will receive it from an external system (maybe they autogenerated it).
