how to merge many cells to one cell with keeping all data

[Valley]

Dear all,

I meet a question about following.
in A column, there are many data(some data are same), and in B column,
there are many relevant data, but they are different, how to merge all
the revelant data to one cell in B column with the same in A column,
thanks in advance!

For example

A B
123 R1
123 R2
123 R3
123 R4
124 L1
124 L2
124 L3
125 C1
125 C2
. .
. .

125 C1 C1 C2
125 C2

but I know to do them with C1=B1&" "&B2&" "&B3&" "&B4 one by one, I
want to know how to do easily.

With the data below starting in row 2 put in C2
=IF(A2=A1,C1&" "&B2,B2)

Now conditionally format C2 and choose the formula is option and
enter
=$A2=$A3

set the font colour to white, or whatever is the colour of your
background and copy C2 down your data


All the cells in column C of course contain data, it's just that you
can't see the other cells.

What you see is the following. It's not quite the same as your exact
requirement which is to have the data on the first row of a 'block' of
similar A values, but you may be able to work with this.

A VBA macro could be written to meet your originally requirement
exactly. If that's what you want just re-post back
