Looking for a Formula

[Rohit_Sonwane]

Respected Sir/Madam

I want to extract first name, middle name, and last name with a space.

But the main problem is there is no delimiter in my data. Only delimiter can be the uppercase word. My data look like this "RohitSanjaySonwane" and I want this "Rohit Sanjay Sonwane" with a space. I want a formula to solve this problem. I am sharing my file.

@Rohit_Sonwane Assuming you have Excel365 here is a formula that will work:

=LET(in,$A1,l,LEN(in),
seq,SEQUENCE(,l),
letter,MID(in,seq,1),
addSpace,IF((CODE(letter)>=CODE("A"))*(CODE(letter)<=CODE("Z"))," "&letter,letter),
out,TRIM(CONCAT(addSpace)),
out)

Create the following custom function in a module in the Visual Basic Editor:

Function ExpandName(s As String) As String
    Dim i As Long
    Dim r As String
    r = Left(s, 1)
    For i = 2 To Len(s)
        If Mid(s, i, 1) <= "Z" Then
            r = r & " "
        End If
        r = r & Mid(s, i, 1)
    Next i
    ExpandName = r
End Function

Enter the following formula in B2:

=ExpandName(A2)

Fill down.

Save the workbook as a macro-enabled workbook (.xlsm).

You'll have to allow macros when you open the workbook.

See the attached version.

In straightforward legacy style

=TRIM(

Another approach:

=LET(
prop,PROPER(A1),
seq_1,SEQUENCE(LEN(A1)),
letters1,MID(A1,seq_1,1),
seq_2,SEQUENCE(LEN(prop)),
letters2,MID(prop,seq_2,1),
ex,EXACT(letters1,letters2),
CONCAT(IF(ex,""," ")&letters1))

Same with recently introduced functions

=TRIM( CONCAT( MAP( MID( A1, SEQUENCE( LEN( A1 ) ),1 ), LAMBDA(v, IF(  EXACT( UPPER(v), v), " " & v, v ) ) ) ) )
