C# 预处理 excel 文件 - 自动检测没有结构数据的行（不是数据表中的数据行），并将其删除

Question

I have lots of excel files like below, in which:

• Yellow zone are the data I want, which I will convert to datatable using EPPlus / ExcelDataReader for further processing
• Red zone are other data that I don't want to include in my datatable, because they are just: notes; blank rows/columns; summary rows (like Subtotal)

Anyone here know the algorithm to delete the red zone or library to pre-process?

I have too many files like this. It takes lots of time to open each file and delete red zone.

Thank you.

Answer 1

The EPPlus worksheet object has 2 functions for this, one for deleting rows, one for deleting columns. Both functions have an overload.

workSheet.DeleteColumn(int column);
workSheet.DeleteColumn(int columnFrom, int columns);

workSheet.DeleteRow(int row);
workSheet.DeleteRow(int rowFrom, int rows);
