I have a spreadsheet with about 18000 lines of data containing multiple
values and blanks beneath each value. Is there a way to auto copy and paste
the value directly beneath each value until you reach the next value?
ie.
Line 1 has a value of 1050
Line 2 to 5 in blank. I want these to have the value of 1050
Line 6 has a vlue of 10654
Line 7 to 18 are blank. I need these to have the value of 10654

Thanks in advance
