 Posted: Wed May 23, 2012 1:22 pm Post subject: [Solved] Reverse the order of rows in very big sheet |
 |
|
I open a some large .csv files with more than 5000 rows. I need an easy and fast way to reverse the order of the rows and I do not have a column with an auto increment or date value that I could use to do that.
Creating another column by dragging the automatic fill handle for 5000 is not very efficient, especially if I have to do every 10 days.
Is there any other way to reverse the order of the rows so that 1 <--> 5000 , 2 <--> 4999 , 3 <--> 4998 and so on. 5000 is a random number. Each file has different number of rows.
Thanks!

I think this works
Create a helper column with this formula it needs to be dragged down well passed your possible maximum row number (but it only needs to be done the once!) which I have taken to be 10,000
| Code: | | =IF(A1=0;"";COUNTA($A$1:$A$10000)-ROW(A1)+1) |
By doing all data sorts using the helper column (which changes with the addition or subtraction of data) as the sort by column, and changing the ascending or descending option, it should do what you want.

If there are no gaps in the adjacent column then double-clicking the fill handle fills down to the 5000th (or whatever) row.
