清理CSV文件

Question

我使用.bat文件來移動每天創建的CSV文件。我現在需要把它清理乾淨：

• 查找和替換「 - 」 0
• 查找和0
• 刪除更換空單元格的所有空間

的CSV只有20行。

Answer 1

不知道，你需要什麼。請解釋更多，如果這不適合你：

for /f "delims=" %%a in (old.csv) do (
    set "line=%%a" 
    setlocal enabledelayedexpansion 
    set "line=!line: =!" 
    set "line=!line:-=0!" 
    >> new.csv echo(!line! 
    endlocal 
) 

Answer 2

批處理文件不是一個很好的工具。你會好得多使用PowerShell：

(Get-Content 'C:\path\to\in.csv') ` 
    -replace ' ', '' ` 
    -replace '-', '0' ` 
    -replace '^,', '0,' ` 
    -replace ',$', ',0' ` 
| % { 
    while ($_ -match ',,') { $_ = $_ -replace ',,', ',0,' } 
    $_ 
} | Out-File 'C:\path\to\out.csv' 

甚至VBScript中：

Set fso = CreateObject("Scripting.FileSystemObject") 

inFilename = "C:\path\to\in.csv" 
outFilename = "C:\path\to\out.csv" 

Set inFile = fso.OpenTextFile(inFilename) 
Set outFile = fso.OpenTextFile(outFilename, 2, True) 

outFile.WriteLine inFile.ReadLine 'write header 
Do Until inFile.AtEndOfStream 
    line = inFile.ReadLine 

    line = Replace(line, " ", "") 
    line = Replace(line, "-", "0") 
    If Left(line, 1) = "," Then line = "0" & line 
    If Right(line, 1) = "," Then line = line & "0" 
    Do While InStr(line, ",,") > 0 
    line = Replace(line, ",,", ",0,") 
    Loop 

    outFile.WriteLine line 
Loop 

inFile.Close 
outFile.Close 

Answer 3

@ECHO OFF 
SETLOCAL 
(
FOR /f "delims=" %%i IN (yourfile.csv) DO (
SET "line=%%i"&CALL :process 
) 
)>newcsv.csv 
GOTO :EOF 

:process 
SET line=%line: =% 
SET line=%line:-=0% 
SET line2=%line% 
SET line=%line:,,=,0,% 
IF NOT "%line%"=="%line2%" GOTO process 
IF "%line:~0,1%"=="," SET line=0%line% 
ECHO %line% 
GOTO :EOF
