如何使用批处理脚本从Excel文件中清除内容？

我试过这个，但它不起作用

type nul > test.xlsx 

Answer 1

excel文件不是文本文件，即使是空文件也包含一些二进制元数据。 试试这个（在第二行你可以设置新文件的名称）：

@echo off
set newFile=new.xslx

certutil -f -decode "%~f0" "%newFile%"

exit /b %errorlevel%

Answer 2

copy nul test.xlsx

应该用零长度文件替换文件，有效删除数据。

Answer 3

检查以下文件夹（might vary depending on your OS and Excel version）：

• C:\Users\All Users\Microsoft\Windows\Templates
• %APPDATA%\Microsoft\Windows\Templates
• %APPDATA%\Microsoft\Excel\XLSTART
• %useprofile%\Templates

可能有一个Excel模板，例如（否则，create i t）

• Book.xlt（.xltx / .xltm）或
• Sheet.xlt（.xltx / .xltm）。

我们假设有一个文件%useprofile%\Templates\Sheet.xltx

然后下一个命令应该做的伎俩：

copy /Y /B "%useprofile%\Templates\Sheet.xltx" test.xlsx
