What word processor (software) are you using? You could use a find/replace system (either the dialog in a word processor, or maybe a script or macro) to replace all new lines (\n) characters with html (<br><br>).
Another trap to watch out for is that:
- Windows operating systems use
\r\nto mark new lines. - Older Apples use
\r. - Serious operating systems use
\n.
That is a “fun” gotcha. Might be best to change:
1.\r\n to \n.
2. Then \r to \n.
3. Finally \n to <br><br>.
