这是我用于从 csv 导出数据并写入 .trn 扩展文件的脚本。代码对 csv 文件数据的某些列正确执行，我的意思是说如果该列没有索引 A 到 Z，代码执行正确，但是当 Z 列之后意味着 AA、AB 等数据出错时。您可以在此处看到的代码:

批处理脚本

@echo off
   set "line1=^%%a,cf,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,,,,,,,,,,,,,"
   set "line2=^%%a,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,qbconid,,,^%%b,,,,,,,,,"
   .......................................................................................
   .......................................................................................
   set "line26=^%%a,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,txtstate,,,^%%z,,,,,,,,,"
   set "line27=^%%a,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,pmtper,,,^%%aa,,,,,,,,,"
   set "line28=^%%a,#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,minfee,^%%ab,,,,,,,,,"
(for /F "tokens=1-28 skip=1 delims=," %%a in ('type "NewPortfolios.csv"') do ( 
        echo %line1%
        echo %line2%
        ............
        ............
        echo %line26%
    echo %line27%
    echo %line28%

    )) >"file.trn"

csv文件数据为:

 A               B             C               AA           AB
$portcode   $qbconId    $name     ....... $pmtper   #minfee
asingh12    123456789   Ajay Singh....... ajay           123

输出是:

asingh12,cf,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,,,,,,,,,,,,,
asingh12,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,qbconid,,,123456789,,,,,,,,,
...................................................................................
asingh12,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,pmtper,,,asingh12a,,,,,,,,,
asingh12,#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,minfee,asingh12b,,,,,,,,,

在上面 2 行中，您可以看到列值出现错误。 正如您所看到的 CSV 数据，最后 2 列的值应该是 ajay 和 123，但它以 asingh12a 和 asingh12b 的形式出现。这些是 a 和 b 的值。它应该来自 AA 和 AB。

有人可以帮我解决这个问题吗？

嗨，Aacini - 希望你过得很好。我再次面临将 .csv 文件转换为 .txt 文件的问题。现在，这一次使用 Quotes(") 从 .csv 获取数据，这就是批处理脚本无法正常运行的原因。请从 .csv 中找到 .txt 格式的示例数据- "_portcode","_qbconId","_name","_address","_city","_state","_zip","_bmeth","_ffee","_brak1","_rate0","_brak2","_rate1 ","_brak3","_rate2","_brak4","_rate3","_brak5","_rate4","_rate5","_bre","_custact","_custody","_qbmgrid","_refby", "_txstate","_pmtper","_minfee"

"schorira","001c000000WtrL1AAJ","9232 Collegeview Cir","Bloomington","MN","55437","T","1000000.0","1.25",,,,,,,, “1.0”，“Robert M. Schofield IRA Rollover”，“Schwab”，“JTB”，“Patrick Stephens”，“MN”，“季刊”，“0”。以前在 .csv 数据中没有引号。请帮帮我。如果你想从我这边得到更多的澄清，请告诉我。提前感谢您的帮助。

嗨，Acini，

到此为止，我们正在等待您的回复。请帮帮我。

最佳答案

编辑:我修复了几个细节，它现在应该可以正确运行了。

编辑 #2:修复了细微错误，并添加了示例

@echo off
set "letter=abcdefghijklmnopqrstuvwxyz"
   set "line1=!a!,cf,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,,,,,,,,,,,,,"
   set "line2=!a!,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,qbconid,,,!b!,,,,,,,,,"

   set "line26=!a!,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,txtstate,,,!z!,,,,,,,,,"
   set "line27=!a!,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,pmtper,,,!aa!,,,,,,,,,"
   set "line28=!a!,#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,minfee,!ab!,,,,,,,,,"
setlocal EnableDelayedExpansion
(for /F "usebackq skip=1 delims=" %%a in ("NewPortfolios.csv") do (
   set i1=0
   set "line=%%a"
   for %%b in ("!line:,=" "!") do for /F "tokens=1,2" %%i in ("!i1! !i2!") do (
      if %%i lss 26 (
         set var=!letter:~%%i,1!
      ) else (
         set var=a!letter:~%%j,1!
      )
      set "!var!=%%~b!
      set /A i1+=1, i2=i1-26
   )
   echo %line1%
   echo %line2%

   echo %line26%
   echo %line27%
   echo %line28%
)) > file.trn

Previous Batch 程序最多可输出 52 列 (a..z aa..az)，但增加此范围非常容易。使用此输入数据:

 A,        B,       C,        D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z, AA,    AB
$portcode,$qbconId,$name,     D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,$pmtper,#minfee
asingh12,123456789,Ajay Singh,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,ajay,123

输出是:

asingh12,cf,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,,,,,,,,,,,,,
asingh12,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,qbconid,,,123456789,,,,,,,,,
asingh12,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,txtstate,,,Z,,,,,,,,,
asingh12,$,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,pmtper,,,ajay,,,,,,,,,
asingh12,#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,y,minfee,123,,,,,,,,,
