使用批处理文件并排合并多个csv文件

问题描述：

我正在寻找两个将多个csv文件合并为一个的文件.但是，我需要将它们合并，以使列并排不会继续. 我的文件每次都有两列，通过提取每个文件的第二列并将其复制到另一个文件中，我将得到一个csv文件，因此我将得到一个带有x列的文件(第二个).

I was looking two merge several csv files into one. However I need them merging so that the columns are side by side not continuing on. My files have two columns each time and I would have one csv files by extracting the 2nd column on each files and copying into another one so I will have a file with x columns (the second one).

例如

File1

File2

Filex

A X
1 x
1 x
1 x

结果

B C X
2 3 x
2 3 x
2 3 x

我发现了这个问题:并排使用合并csv文件批处理文件

但是它仅用于两个文件，并且不提取任何内容.

but it's just for two files and it doesn't extract anything.

谢谢.

答

@ECHO OFF
SETLOCAL enabledelayedexpansion
:: remove variables starting $
FOR  /F "delims==" %%a In ('set $ 2^>Nul') DO SET "%%a="
SET /a $count=0
FOR %%a IN (q28850167*.txt) DO (
 FOR  /f "tokens=1,2*delims=: " %%b IN ('findstr /n /r "^" "%%a"') DO (
  SET $%%b=!$%%b! %%d
  IF !$count! LSS %%b SET /a $count=%%b
 )
)
(
FOR /L %%a IN (1,1,%$count%) DO ECHO(!$%%a:~1!
)>newfile.txt


GOTO :EOF

我使用了名为q28850167*.txt的文件，其中包含用于测试的数据.
产生newfile.txt

I used files named q28850167*.txt containing your data for my testing.
Produces newfile.txt

清除所有以$

对于每个与掩码匹配的文件，请通过findstr/n处理每一行，以将number :应用于每一行的开头.选择:和 Space 作为分隔符的第一和第三+列，并追加到变量$linenumber跟踪$count中的最高行号.

For each file matching the mask, process each line through findstr/n to apply number : to the start of each line. Select the first and third+ columns using : and Space as separators and append to variable $linenumber Keep track of the highest line number in $count.

然后只需从存储的数据中复制每一行.

Then simply reproduce each line from the stored data.
