## How to sum all digits in a number in Excel?

If you have a cell which contains a value, and now, you want to add all the digits together of the cell. For example, if you have the value 12345 in a cell, you want to do this calculation: 1+2+3+4+5, and get the value 15. Are there any good ways for you to sum all digits of a number in Excel?

#### Sum all digits of a number in a cell with formulas

Without adding the digits one by one manually, the following formulas can help you get the summation of a cell quickly.

1. Please enter or copy any one of the following formulas into a blank cell to output the result:

=SUMPRODUCT(1*MID(A2,ROW(INDIRECT("1:"&LEN(A2))),1))
=SUM(INDEX(1*(MID(A2,ROW(INDIRECT("1:"&LEN(A2))),1)),,))

2. Then press Enter key to return the result, and select the cell C2, then drag the fill handle over to the range that you want to apply this formula, and you will get the summation of digits of each cell number.See screenshot:

Notes:

• In the above formulas, A2 is the cell contains the number which you want to sum its digits.
• If there is negative sign or a decimal point in the number, the formulas return a #VALUE! error.

#### Sum all digits of a number in a cell with User Defined Function

To add up all digits of a cell number, the following VBA code also can help you.

1. Hold down the ALT + F11 keys, and it opens the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following code in the Module Window.

VBA code: Sum all digits of a cell number

`````` Function SumDigits(Number As String) As Integer
'Updateby Extendoffice
Dim x As Integer, C As String
For x = 1 To Len(Number)
C = Mid(Number, x, 1)
If IsNumeric(C) Then SumDigits = SumDigits + C
Next
End Function
``````

3. Then save and close this code, return to the worksheet, and enter this formula =SumDigits(A2) into a blank cell, Then drag the fill handle down to the cells that you want to contain this formula, you will get the following result:

Bonjour,
Je cherchais justement cette solution c.à.d. comment faire la somme des chiffres d'un nombre (de 4 chiffres) sur excel et je suis tombé sur ce site. Je suis en profonde admiration devant l'intelligence de certains qui ont trouvé des formules de ouf. Malheureusement, je ne suis pas à ce niveau pour les mettre en pratique. Je me suis dit (car j'aime me parler, comme ça, j'ai toujours raison LOL) que pourquoi chercher compliqué quand on peut faire plus simple et j'ai trouvé une solution qui n'est pas élégante (OK je ne suis pas Einstein) et qui marche. Que veut on de plus ! Je vous la donne ici.
Je prends un exemple avec un nombre à 4 chiffres mais vous pouvez ajouter autant de chiffres que vous voulez. Disons que ce nombre est dans la cellule A2 pour l'exemple :
=STXT(\$A\$2;1;1)+STXT(\$A\$2;2;1)+STXT(\$A\$2;3;1)+STXT(\$A\$2;4;1)
J'ai mis des \$ pour pouvoir copier plus facilement et ensuite je n'ai qu'à changer le rang du chiffre, dans mon cas 1, 2, 3, 4 et vous pouvez allez aussi loin que vous voulez
En anglais, vous remplacez STXT par MID et en allemand par TEIL
Si vous voulez la somme du résultat (dans la cellule A3 par ex.), vous faites la même chose en remplaçant A2 par A3.
Voila
Julien

Já procurei mais não acho por nada eu queira fazer uma planilha que o resultado da soma final reduz o número a 1 dígito. Por exemplo o resultado deu 7+6=13 e ele virasse 1+3= 4

I play KillerSudoku: If I have n number of sums (not the total or answer) but I have say 2 or 3 or more empty cells with number possibilities who's sum totals 15; say, the total is 15 and I have 4 empty squares that all live in the same cage (meaning non-repeating), how do I show all possible sums: ie, 2+3+6+4, or 3+5+1+6, or 3+4+6+1 and so on. Also, I need to sometimes show all possible sums with repeating. Can this be done in Excel
