Parsing out First and Last name from Excel field

问题

I have a field (column) in excel in the format of "LastName, FirstName MiddleInitial" with a space between the comma after the last name and the first name and a second space between the middle initial and the first name (no comma after the first name). Is there a way to identify which cells have a middle initial on the right hand side and then eliminate the middle initial for all cells such that the output will look like "LastName, FirstName"?

Thanks!

What you want to do is to be able to parse the field into multiple fields, and then rejoin then with a simple excel formula. To take a field and put it into multiple columns you can use the following approach for "Text to Columns"

Text to Columns

Once you have 3 columns of text, you can group the first two together by using a formula like =A1&", "&B1 in the column you want to have the value. (In my example, the last name would be in A1, and first name in B1)

You could also do it as a cell formula without changing your original data. I built this up using the models presented on How to split a string based on “:” in MS-Excel?, over at SuperUser. Assuming you have a name (Public, John Q) in a1:

=LEFT(A1,FIND(" ",A1)) & LEFT(MID(A1,FIND(" ",A1)+1,LEN(A1)),IFERROR(FIND(" ",MID(A1,FIND(" ",A1)+1,LEN(A1)))-1,LEN(MID(A1,FIND(" ",A1)+1,LEN(A1)))))

It looks very complicated, but really isn't:

Using these two components:

• Get everything to the left of the first space in a string: LEFT(A1,FIND(" ",A1))
• Get everything to the right of the first space in a string: MID(A1,FIND(" ",A1)+1,LEN(A1)))

We can grab these pieces:

• Get the last name: LEFT(A1,FIND(",",A1)+1)

• Get the first name and middle name: MID(A1,FIND(" ",A1)+1,LEN(A1)))

Then recurse by putting the "left of a space" construction around the "right of a string" construction:

MID( LEFT(A1,FIND(",",A1)+1) ,FIND(" ", LEFT(A1,FIND(",",A1)+1) )+1,LEN( LEFT(A1,FIND(",",A1)+1) )))

Unless there is no second space (when there's no middle name.) That's what the Iferror is for - in that case, you want the entire length of what you got after the first space:

• LEFT(MID(A1,FIND(" ",A1)+1,LEN(A1)),IFERROR(FIND(" ",MID(A1,FIND(" ",A1)+1,LEN(A1)))-1,LEN(MID(A1,FIND(" ",A1)+1,LEN(A1)))))

Put them together for lastname, firstname:

• =LEFT(A1,FIND(" ",A1)) & LEFT(MID(A1,FIND(" ",A1)+1,LEN(A1)),IFERROR(FIND(" ",MID(A1,FIND(" ",A1)+1,LEN(A1)))-1,LEN(MID(A1,FIND(" ",A1)+1,LEN(A1)))))
