Add paragraph spacing to product descriptions in excel spreadsheet - approx 300 descriptions to edit

Hello freelancers! I have a large data file with approximately 300 product descriptions that need to be formatted. The descriptions are currently one long paragraph of text. I would like paragraph spacing added and for product specifications (size, colour etc) each specification should appear on a new line. It is a simple and repetitive, but time consuming task! It only requires the use of Alt+enter to add spaces at the appropriate points. I have formatted approximately 70 descriptions already as a guide. I estimate that amending the remainder of the file would take no more than 3 to 5 hours depending on how quickly you can scan and format each paragraph. You will need to read the description in detail to find the appropriate paragraph and specification break points. This will require a good grasp of English in order to read and understand the description. Please note that this is for an adult sex toys store, so you will need to be comfortable with non-explicit, but sexual product related text.
