我对PowerShell和RegEx非常陌生，并且非常乐意为您提供帮助。我有一个文件，＆＃34; print.txt＆＃34;它有大约35,000行。我被要求找到一种方法将其转换为CSV以便在Excel中进一步操作。
不幸的是我无法控制print.txt的格式，所以我按原样坚持了。

有人会关心这个吗？我已经在这里阅读了许多类似的请求，但在我自己的实现中没有多少运气。
答案 0 :(得分：1)
只是一个开始，但你看到这导致的地方:)以下的正则表达式匹配前两行（在自由间隔模式下）
\#(?P<cycle>\d+)\s
(?P<date>[\d/]+)\s
(?P<time>[\d:]+)\s+
Total:\s(?P<total>[\d.]+)[-\s]+
RCPE:\s+(?P<rcpe>\d+)\s
ID:\s(?P<id>\d+)\s
WKOD:\s+(?P<wkod>\d+)\s
OPRT:\s+(?P<oprt>\d+)\s
TARE:\s(?P<tare>[.\d]+)
之后，你只需将各个部分粘在一起。见a demo on regex101.com。除此之外，@ Bacon Bits可能是对的 - 您可能更适合搜索自由职业者。
答案 1 :(得分：0)
我可能会使用正则表达式，但这里有一些替代方案。
如果您有Powershell 5.0，可以尝试使用易于创建的模板ConvertFrom-String。

但是，我在使用Retry行时遇到了问题，因为它在每个字段中都没有值。如果你设法解决这个问题，那么如果你对写正则表达式感到不舒服，这是一个很好的选择。
您还可以使用拆分和大量硬编码值。
