Those are the full values, so $78.3k, $344.3k, $1.5k, etc. I want them to be in millions though, and not just displayed as millions (like Format Cell > Custom) but to actually change the raw data. So the first one would become 0.0078344, second would be 0.344345, etc.
Can you use the formula =(A1)/1000000 in another cell, click and drag down so it auto-populates all the cells with the 'millionified' values? If you need to overwrite the original values with the new ones you can just copy/paste the data (as opposed to the formula), I'm sure there's an option for that.
