I need to delete every second row in my spreadsheet - the rows are blank.
There are 30,000 rows so I don't want to do it manually - is there an easy
way to delete every second (or every blank) row?
Take a parallel column and insert the number 1 in the first cell. On the
following cell below insert the number 2. Use copy and paste to insert 1 and
2 into each successive cell (this won't take too long as each time you copy
and paste you'll be copying double the number of cells you copied the
previous time.) Keep going till all 30,000 cells in your column have a 1 or
a 2 in going in the order 1,2,1,2,1,2 etc.
Then do a 'sort' on the spreadsheet by that column so that all the 1's come
first and the 2's come second. Voila.
