在 VBA 中逐行读取/解析文本文件 [英] Read/Parse text file line by line in VBA

问题描述

我正在尝试使用 VBA 解析文本文档并返回文本文件中给出的路径.例如，文本文件看起来像:

I'm trying to parse a text document using VBA and return the path given in the text file. For example, the text file would look like:

*Blah blah instructions
*Blah blah instructions on line 2
G:\Folder...data.xls
D:\AnotherFolder...moredata.xls

我希望 VBA 一次加载 1 行，如果它以 * 开头，则移动到下一行(类似于被注释的那一行).对于带有文件路径的行，我想将该路径写入单元格，例如 A2 表示第一个路径，B2 表示下一个路径，等等.

I want the VBA to load 1 line at a time, and if it starts with a * then move to the next line (similar to that line being commented). For the lines with a file path, I want to write that path to cell, say A2 for the first path, B2 for the next, etc.

我希望回答的主要问题是:

The main things I was hoping to have answered were:

1. 使用 VBA 阅读文本文件的最佳/简单方法是什么?
2. 我该如何逐行执行此操作?

推荐答案

对于文本文件最基本的读取，使用 open

for the most basic read of a text file, use open

示例:

Dim FileNum As Integer
Dim DataLine As String

FileNum = FreeFile()
Open "Filename" For Input As #FileNum

While Not EOF(FileNum)
    Line Input #FileNum, DataLine ' read in data 1 line at a time
    ' decide what to do with dataline, 
    ' depending on what processing you need to do for each case
Wend
