Features explained
Join multiple lines into one line
Turns text written on many lines into a single line, so you do not have to delete line breaks by hand.
Join with space or custom separator
The Join with option sets what goes between the lines. The default is a single space.
Keep or remove empty lines
Keep empty lines is off by default, so blank lines are left out. Switch it on to keep them.
Copy result to clipboard
One click copies the joined text. The button changes to Copied! so you know it worked.
Download as .txt
Saves the result as a plain text file, useful for longer text you want to keep.
Load example
Fills the input with sample text so you can see how the tool works before using your own.
Reset and clear
The Clear button resets the tool, which is handy when you want to join a new list.
Runs in the page
The text is processed with JavaScript in the page. No request to a server was found in the tool code.
What can you use it for?
Turn a column into one line
Copy a column of names, IDs or emails from a spreadsheet and join it into one line.
Fix text copied from a PDF or email
Text copied from a PDF or an email often has a line break at the end of every line. Join the lines to get a clean paragraph.
Prepare lists for forms and search boxes
Some forms and search fields accept only one line. Join your list first, then paste it in.
Clean up notes and keyword lists
Join keyword, tag or hashtag lists that you wrote one per line, and skip the empty lines.
Make code and config values
Join a list of values with your chosen separator before you paste it into a script, query or config file.

Tips
- Check the Join with value before you copy. A space and a comma give very different results.
- If your result has gaps, make sure Keep empty lines is off.
- Use Load example first if you want to see how the options change the result.
- Press Clear before you paste a new list so old text does not mix in.
