Parsing Data Strings Into Columns

I have a spreadsheet that gathers information from multiple cells and strings the data into a long string - each piece of data broken by a comma in the string.

In another spreadsheet, I copy this data string into column A on sheet 1 - starting on row 2 and down.

On sheet 2 - and this is where I need help - I would like to have a macro that will take each data string on Sheet 1 column A and parse it out into multiple columns but the same row on Sheet 2.

ColumnA Row2 Sheet1 -> changing to many columns on Sheet2 but still on the same row.

The data string always represents the same number of data components - its just a matter of breaking it out and placing each data piece into its own column.
