I have a column in an excel spreadsheet (currently) formatted in general which is essentially a number i.e. 456789, in the column next to it I need a formula whereby it adds a "." 3 characters in from the right, i.e. 456789 needs to become 4567.89

any ideas how this could be done?

Try This
=LEFT(A1,LEN(A1)-2)&"."&RIGHT(A1,2)

Open in new window

This is as per your result but you said
it adds a "." 3 characters in from the right

then there will be different formula. pls clarify.

Assuming your number is in cell A1:

=LEFT(A1,LEN(A1)-2)&"."&RIGHT(A1,2)

If the number is literally a number, just dividinbg by 100 will add the decimal point. This can then be converted to text if so required:

=A2/100

or

=TEXT(A2/100,"0000.00")

Thanks

for both I get a formula error, I changed the cells accordinly. Could this be to do with how the current column is formatted, and the formula column is formatted? both are currently formatted "general".

Is the contents of the cell just the 6 digits or does it have leading/trailing spaces?

If extract from another system (assumed link to other question about 7/8 characters) then it may be a non-visible character at the start of the cell. This may not be a normal "space" character which can be renoved using trim, you may have to use other forms of cleansing.

Use the following to determine which character is at the start of the cell:

=CODE(LEFT(A2,1))

A normal space will give the number 32.

That error message normally suggests you have missed something from the formula and Excel is unable to determine and correct the error automatically, eg missing brackets where it is not obvious where the missing brackets should be or inclusion of text within double quotes that are not closed out.

Which nationality version of Excel are you using? Some versions require semi-colon ";" separator in the formula rather than comma ",".

anyone got a theory why that formula would work on one installation of excel and not another. could it be a global setting in excel affecting this?

normal formulas i.e. =a1/2 work, it just seems to be text based formulas like len, right, left etc.

if you don't care about changing the underlying number, just how it "appears", then apply a Custom format to the cells of
0000"."00

if you DO want to change the numbers permanently, find a spare cell, put 100 in it, copy it,
select your number range, choose Paste Special - and then choose the Divide option.
Job Done.
