From my own previous experience, using a global search and replace for the paragraph indent's number of spaces to "<p>," minimal tags at the beginning and end, and renaming the text file to the html extension mostly works fine - html rendering ignores line breaks in the input file without tags to make it pay attention. At most you might need another search and replace on newline/carriage return to add a space if there aren't any at the end of each line.
