I have a spreadsheet with many columns. The columns are all a small standard width. Double-clicking the partition line between columns will expand the column width to encompass the longest string in that column.

Is there a shortcut to perform this operation on every column in the spreadsheet?

Click where the row and column headers meet, this will select the entire sheet, like so:

alt text

Then double-click any one of the column partition lines.

I do this all the time, and it's as quick as you can get.

I don't know about shortcut. I use menu.
1) Select The Full Spreadsheet
2) Select Format
3) Column
4) Autofit Selection

+1 I like this solution because it works on whatever range you select and you can exclude, for instance, titles that you want to span many columns. –  dkusleika Jul 8 '10 at 17:02
Sometimes for long strings the autofit does not expand to fit the longest line in that column. navigating this tip brought me to the other options of manually setting the width which was useful. –  Paul Aug 12 '14 at 14:51
And for particularly long strings there are times when Excel just fails. Although, I haven't run into this yet with the newer versions. –  Dave Aug 13 '14 at 17:11

Try selecting everything (CTRL + A twice rapidly, or just select the columns you want), and then double-click a partition line. In Excel 2007, that solution seems to work just fine; in other words, it automatically sizes each column to its own longest string.

doesn't work in 2003 –  Dave Jul 8 '10 at 16:18
It does work in 2003. In both versions, you have to make sure the whole column is selected, not just a range of cells. –  dkusleika Jul 8 '10 at 17:01

Ctrl+A to select all cells, then press Alt+H, O, I.

Is that working in all excel versions? –  boboes Feb 19 at 8:30

Ctrl-A on the Spreadsheet. Click Format=>Row=>Height Enter 409 or any other value. Click OK See the Magic

The question was how to adjust the size of all columns, not how to make the rows gigantic. –  MattDMo Aug 22 '13 at 2:06
