- Hyphens
- Left as they are on this page, so "well-" + "known" isn't merged into one word

Join lines: what to know
This page starts the remove line breaks for this case. For every option and how to use it, see the remove line breaks.
When joining lines helps
Some text needs to be on one line to work: a SQL query pasted into a log search, a long command for a terminal, an address for a form field that won't accept line breaks, or a list of tags. The example on the page is a short SQL query spread over five indented lines.
Unlike the main remove line breaks tool, this page joins everything, including blank lines, and doesn't rejoin hyphenated words. That keeps code, file paths and ranges like "2025-" + "2026" exactly as you wrote them.
Joining with something other than a space
Pick Replace with to join lines with a comma, a semicolon, a pipe or anything you type. Use \t for a tab, which pastes into a spreadsheet as separate cells across one row.
Text editors can do it too. In Vim, J joins the line below onto the current one. In Notepad++, select the lines and choose Edit > Line Operations > Join Lines. Use this page when the text isn't in an editor, or you want the result without opening one.
Questions
How do I merge two lines into one?
Paste both lines in the box. They come back as one line with a space between them, ready to copy.
How can I merge two paragraphs into one?
Use this page as it opens: blank lines are dropped too, so two paragraphs become one line. To keep paragraphs apart, switch to keep paragraphs.
How do I join lines in Notepad++?
Select the lines, then choose Edit > Line Operations > Join Lines. Notepad++ replaces each line ending in the selection with a single space, as this page does.
