除了一些关键字之外，还可以获取句子中每个单词的首字母
我认为这是一个棘手的问题，但我想听听有没有人可以有解决办法。
我需要创build一个公式来获取名称列表中每个单词的第一个字母，例如：
中国电子科技大学
电子科技大学（如果可能，应避免使用''''，''和'，'a'）
我到目前为止所尝试的是：
=(LEFT(H2)&MID(H2,FIND("#",SUBSTITUTE(H2&" "," ","#",1))+1,1)&MID(H2,FIND("#",SUBSTITUTE(H2&" "," ","#",2))+1,1))&J2&M2 好问题！ 我认为你最好的select是使用VBA创build你自己的function。 将下面的代码添加到VBA编辑器中的新模块中，您可以在工作表上使用以下function：
=FirstLetters(A1)
根据你的例子，这将返回UESTC
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，我发现了一个有点可笑的答案，它基本上连接了很多ifs来循环每个单词（VBA在这里更容易）。 下面的公式可达9个字。 如果你的string有更多，你只需要添加一些FIND(A1," ")+1 。 如果公式不适合你，请删除它的回报。

步骤1：
使用替代来删除你想丢弃的东西。
句法：
SUBSTITUTE(text, old_text, new_text, [instance_num])
第2步：
在任何单元格中保持值1（假设B1）。
第3步：
用下面的公式来得到第一个字母。
=IF(LEN(A1)>=B1,RIGHT(LEFT(A1,B1),1)," ")
A1是你的input，B1的值是1.如果你想要第一个字母。 如果你想要第二个字母B1的值应该是2 ..等等。
如果你想有第一个字，那么：
=LEFT(A1,SEARCH(" ",A1)-1)
如果您使用具有可用CONCATfunction的Excel 2016或365，则以下公式将适用于任意长度的string：
=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),""))
请注意，这是一个数组公式，必须通过双击进入单元格，粘贴公式，然后按CTRL+SHIFT+ENTER
它将始终包含第一个单词的第一个字母，即使它是要排除的关键字之一。 所有其他关键字被排除。 通常，第一个单词的第一个字母应该总是包含在内，但是如果您还需要删除它，我可以进一步修改公式。
