Roll multiple rows of text into one row

Often when copying and pasting text into Excel 2003 paragraphs and sentences spread over multiples rows of Excel.

It would be much nicer to keep them all in one cell, so I can then apply wrap text format to make everything look nice.

The attached file has the first three rows showing how I would like it to look, but I have thus far only achieved it by the tedious process of copying and pasting each row into the top cell.

In row 6 and below you can see the irritating way Excel pastes text into itself.

Desperate for some help, would greatly improve efficiency!

Thank-you!
