在Excel中用空格提取字符串的第一个字符

我试图将左侧的字符（字母）提取到一个单独的列中。我已经尝试了

=MID（A1,1，SEARCH（“，A1,1））

，这适用于除ARNC1和GALE1字符串之外的所有内容

ARNC1 01202017 C 13
AAPL 12232016 C 113
CMI 12232016 C 135
JCP 12302016 C 10.5
PSX 12232016 C 88
GALE1 01192018 C 3

例如，我需要看看

ARNC
AAPL
CMI
JCP
PSX
GALE

谢谢，

即使已经有了答案，也只是免费的：

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(MID(A1,1,SEARCH(" ",A1,1)),1,""),2,""),3,""),4,""),5,""),6,""),7,""),8,""),9,""),0,"")

=MID(A1,1,MIN(FIND({0,1,2,3,4,5,6,7,8,9," "},A1&"0123456789 "))-1)
