FAQ
What does “Newline (no change)” do?
It keeps each item on its own line. Use it to compare results or copy without changing formatting.
Can I use a custom separator?
Yes. Type any separator (for example |, ;, or / ) and click “Join”.
Will it remove empty lines?
It joins the lines you provide. If you want to remove blank lines or extra whitespace first, use “Remove Extra Spaces”.
Does it add quotes for CSV?
No. It just joins text with a separator. For strict CSV quoting rules, use a dedicated CSV tool.
Is my text stored anywhere?
No. The tool runs locally in your browser and doesn’t upload your text.
