獲取除關鍵詞以外的每個單詞的第一個字母

Question

我認爲這個問題很棘手，但我想聽聽是否有人可能有解決方案。

我需要創建拿起在名稱列表中的每個單詞的第一個字母的公式，例如：

中國電子科技大學

電子科大（下稱 ''， '中'， '和'， 'A'，以避免可能的話）

我試了一下，到目前爲止：

=(LEFT(H2)&MID(H2,FIND("#",SUBSTITUTE(H2&" "," ","#",1))+1,1)&MID(H2,FIND("#",SUBSTITUTE(H2&" "," ","#",2))+1,1))&J2&M2 

Answer 1

步驟1：

使用替代刪除任何你想放棄。

語法：

SUBSTITUTE(text, old_text, new_text, [instance_num]) 

第二步：

在任何細胞保持值1（假設B1）。

第3步：

使用下面的公式得到第一個字母。

=IF(LEN(A1)>=B1,RIGHT(LEFT(A1,B1),1)," ") 

A1是你的輸入，B1的值爲1.如果你想要第一個字母。如果你想要第二個字母B1的值應該是2 ..等等。

如果你想有那麼第一個字：

=LEFT(A1,SEARCH(" ",A1)-1) 

Answer 2

問得好！我認爲你最好的選擇是使用VBA創建你自己的功能。下面的代碼添加到一個新的模塊中的VBA編輯器，你可以使用該功能對您的工作表是這樣的：

=FirstLetters(A1) 

這將返回UESTC，按你的例子​​

Function FirstLetters(str As String) 
    Dim words As Variant 
    Dim resultStr As String 
    Dim i As Integer 

    words = Split(str) 
    For i = 0 To UBound(words) 
     Select Case words(i) 
      Case "the", "of", "and", "a" 
       'ignore 
      Case Else 
       resultStr = resultStr & Left(words(i), 1) 
     End Select 
    Next i 

    FirstLetters = UCase(resultStr) 
End Function

好吧，我發現了一個有點荒謬的答案，它基本上連接了很多ifs來循環每個單詞（VBA在這裏更容易）。以下公式最多9個字。如果你的字符串有更多，你只需要添加一些FIND(A1," ")+1。如果該公式不適用於您，請刪除其中的退貨。

=IFERROR(UPPER(
IF(LEN(A1)-LEN(SUBSTITUTE(A1," ",""))+1>=1,IFERROR(IF(SUM(--(LEFT(A1,FIND(" ",A1)-1)={"the","of","a","and"})),"",LEFT(A1,1)),LEFT(A1,1)),"")& 
IF(LEN(A1)-LEN(SUBSTITUTE(A1," ",""))+1>=2,IF(SUM(--(MID(A1,FIND(" ",A1)+1,IFERROR(FIND(" ",A1,FIND(" ",A1)+1),LEN(A1))-(FIND(" ",A1)+1))={"the","of","a","and"})),"",MID(A1,FIND(" ",A1)+1,1)),"")& 
IF(LEN(A1)-LEN(SUBSTITUTE(A1," ",""))+1>=3,IF(SUM(--(MID(A1,FIND(" ",A1,FIND(" ",A1)+1)+1,IFERROR(FIND(" ",A1,FIND(" ",A1,FIND(" ",A1)+1)+1),LEN(A1))-(FIND(" ",A1,FIND(" ",A1)+1)+1))={"the","of","a","and"})),"",MID(A1,FIND(" ",A1,FIND(" ",A1)+1)+1,1)),"")&

),"") 

Answer 4

如果你使用的是Excel 2016或365，其中有可用的CONCAT功能，下面的公式將字符串的任意長度的工作：

=LEFT(A1,1) & CONCAT(IF(MID(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1," the "," "), " of "," "), " a "," "), " and ", " "),ROW(OFFSET($A$1,0,0,LEN(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1," the "," "), " of "," "), " a "," "), " and ", " ")),1)),1)=" ",MID(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1," the "," "), " of "," "), " a "," "), " and ", " "),ROW(OFFSET($A$1,1,0,LEN(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1," the "," "), " of "," "), " a "," "), " and ", " ")),1)),1),"")) 

注意，這是一個數組公式，必須通過雙擊進入單元格，粘貼公式，然後按CTRL+SHIFT+ENTER

它將始終包含第一個單詞的第一個字母，即使它是要排除的關鍵字之一。其他所有關鍵字均被排除。通常，第一個單詞的第一個字母應該總是包含在內，但是如果您還需要將其刪除，我可以進一步修改該公式。
