Text Line Joiner
Paste bounded text, choose exactly how line endings and blank lines are handled, then copy the result.
A QUICK WALKTHROUGH
How to use this tool
- Enter text up to 1 MB.
- Choose a literal delimiter and line options.
- Generate and copy the joined text.
Predictable line handling
CRLF, LF, and CR are recognized. Trim removes surrounding whitespace from each line; filter blank lines removes lines that are empty after trimming. Preserve mode keeps line content while still normalizing line boundaries for joining.
Literal delimiter and local limit
The delimiter is inserted literally and is not treated as a regular expression. Input is limited to 1 MB of UTF-8 text and processing stays in the browser.
GOOD TO KNOW
Common questions
Are delimiters interpreted as regular expressions?
No. The delimiter is inserted as literal text.
What happens to CRLF and CR?
They are recognized as line endings along with LF.
Can blank lines be removed?
Yes. Enable trimming and blank-line filtering to remove whitespace-only lines.
