Autofill Entire Row With Data From Above Over Entire Spreadsheet

I'm trying to autofill a series of rows (that are blank) with data from an above row. I want to autofill the row in its entirety, not just filling in blank cells.

For instance (assuming comma is a new column). Colors listed are just a data example. Space between commas indicates a blank cell:

142, RED, GREEN, , YELLOW, , BLACK, PURPLE
(blank row)
142, GREEN, RED, ,BLACK, , PINK, ,
(blank row)
(blank row)
(blank row)
154, YELLOW, BLACK, , GRAY, , PURPLE, RED
(blank row)
(blank row)

So rather than it just completing the task in one desired cell, it would complete the task over the entire spreadsheet. Data spread can be as far as row 500 and column BY, so you can see how a copy + paste or a drag would get monotonous.

Another small example data set:

1,1,1453,0,10,-35
(blank row)
(blank row)
0,0,1448,0, ,-35
(blank row)
1, ,1443,1,3,-36
1,2,1408,2,7, ,
(blank row)
(blank row)
(blank row)
1,2, ,2,7,-39
(blank row)
(blank row)
1,3,1344,1,10,31

And column A will always have data (unless the row is completely blank.
