Macro To Search A Column And Copy Row Data

I have a dataset that is large. I want to write a macro program that checks the number in cell A1, copies the number and then the rows contents to another worksheet/spreadsheet. Then jumps to cell A2 and if the number is different to that of A1 copy the data of that entire row over from that row to the next worksheet/spreadsheet. If the number is the same as A1 then jump over to A3

Then continue this process but rather than comparing it to A1, compare it to the new number that has been found in coloumn A.

For example

7 A
7 A
6 AB
7 A

So starting at the first line then jumping the next one then to 6 and finally 7.
