Hi guys,

1) I have a column of cells filled with different numbers. I want to increase the number for each of these cells by 1. Is there any way of doing it at once?



2) If I want to combine the cells in column A and B for multiple rows. How to do it at once instead of doing it row by row?

thx.

1) Enter 1 in an empty cell somewhere and copy it.
Select the range or the cells you want increased.
Right Click - Paste Special -Check "add" - OK

2) In C1 enter =A1&B1 then drag down as needed or double click the cross-hair at the right lower corner of the selected cell

1) is very useful when the number of cells to modify is not too large for click & drag (sometimes I need to handle up to a thousand cells in a single column).

2) Not sure what C1 is. The only better way I currently use is to combine the cells in the 1st row, and then click & drag the cross-hair down for all succeeding rows. But like again, that wouldn't be a good way for handling a very large number of rows.

Here's a general method for copying a formula from one cell to many. I'll pretend you're copying that value 1 that Peco told you about, but it'll work with anything.

Let's say you have continuous data (ie no empty cells) in column A, running from row 2 down to row 99 999. You want to create a 1 in B2:B99999. Do this:

1. Enter 1 in B2.
2. Copy B2. I usually do that by hitting <Ctrl-Ins>, because I'm a grizzled old Windows user; but you can use <Ctrl-C>, or <Alt-H>,C, or mouse to the Copy icon, or whatever pleases you.
3. Now there's a dotted line blinking around B2, showing that it's ready to be copied somewhere. Don't complete the copy yet; just hit <Left> on in some other way move the cursor to A2, or indeed to anywhere between A2 and A99999.
4. Hit and release the <End> key.
5. Hit and release the <Down> key.
6. If there were no empty cells between A2 and A99999, you're now at the last cell in the range, ie A99999. Hit <Right> or in some other way move the selection one column to the right, back to B99999.
7. Hold down the <Shift> key.
8. While still holding down <Shift>, strike and release <End>
9. Still not releasing <Shift>, strike and release <Up>.
10. You're now back at B2 where you started, but you have the whole range B2:B99999 selected—and B2 still has the blinking border around it indicating that it's ready to be copied. So hit <Enter> to copy B2 to the whole range B2:B99999. (The fact that it'll copy over itself is of no consequence.

There, it's done. I took 10 careful steps to describe the whole thing, but if you know all the keystrokes you can collapse them mentally into just this:

1. Copy the formula at the top.
2. Move to your index column and <End><Down> to the bottom of the range.
3. Move back to your formula column and <Shift-<End,Up>> to the top again.
4. Complete the copy with <Enter>.

This obviates having to scroll down and up a long, long time. But it depends on there being at least one column in your data that is unbroken from top to bottom.

Please read my answer before answering. I NEVER talked about dragging, only selecting your range before Paste Special Add

Select the first cell - While holding down the Ctrl and the Shift key hit the down arrow. Voilà -

As for your second request, I do not understand what you want.
EDIT : on second thought i added you to my "ignore list"

<End><Down> to reach the bottom of column A. <<Shift>+hold><End><Up> to select the same range in column B. <Enter> to paste the copied data in all B cells.
