I have 150000 observations, which I am trying to work with in LibreOffice (new name for OpenOffice.org). The main thing I want to do is to have some formula calculated for all of these observations. Different parameters of the observations are in the first 4 columns, so I wrote a function in the following column in row 2 that uses the previous columns. Now I need to copy the formula all the way down to row 150000. I tried using the mouse (as usual), but this is just way to slow. Is there a faster way to mark everything all the way to the bottom?

    Please, do note that LibreOffice is a completely separate piece of software. You're distro's repositories may have replaced it (I think mine has), but that they are developed by totally different groups. – new123456 Oct 20 '11 at 1:34

Yes - you can define the range of selected cells manually, and after that, "fill" the formula into all selected cells. This may take some time if the formula is applied to 150,000 data sets, so maybe you should proceed stepwise (applying for rows 1 to 50,000, 51.000 to 100,000 and so on - or use a database as proposed by m0skit0).

The cell that's currently selected is displayed in the "Name Box": Name Box

You can modify the selection by simply clicking into the "Name Box" and change its value: Name Box 2

After you've set the selection's range this way, you can copy the the formula from cell B1 down into all selected cells using Fill -> Down from Edit menu: Fill - Down

or using the shortcut CTRL+D: this operation will only affect the selected cells; in my example: B1:B3.

As result, the formula is pasted only inside the cell range defined in the "Name Box".

  • Very nice answer, complete and with images made it a really good answer. – PhoneixS Jun 11 '13 at 14:46

Try double-clicking on the bottom right hand corner of the cell (ie on the box that you would otherwise drag).

Select a formula. Copy it. Select all cells where you want to copy it. Paste.

This is a keyboard-only solution, which I've used for many years. It's extremely fast, and comes naturally when you've used it a few times:

Go to an adjacent column that has no blank rows in it, use CTRL + down arrow to go to the bottom row of the dataset.

Use right (or left) arrow to move to the bottom of the blank column that has your formula in the top row, then type a period (or any other character) in that last row.

Use Up Arrow, then Ctrl + Up Arrow to go to up the cell with your formula in it.

Hold down Ctrl + Shift, and Down Arrow to select the whole column down to, and including, the period you typed at the bottom.

Type Ctrl + d to fill the formula down the column (this make take a few seconds in a very large dataset).

Type Ctrl + s to save your changes, of course.
