Writing Utility
Join Lines
Turn a vertical list into one continuous line using the exact separator you choose.
Source and separator
Blank lines are skipped. Nonblank line order and content are preserved.
Enter one item per line. Existing spaces inside each nonblank line are preserved.
Inserted only between joined items. Spaces and symbols are preserved exactly; an empty separator is allowed.
Add source lines and choose a separator.
Joined result
The complete single-line artifact remains separate from the original source.
No joining has been run yet.
Runs in this browser. No upload by this tool. Your original lines remain unchanged. Review the result before sharing.
How to use Join Lines
- Paste or type the source text with one item per line.
- Enter the exact separator to place between items.
- Keep any spaces in the Separator field that you want in the result.
- Select Join lines and review the separate single-line artifact.
- Check that blank lines were skipped and item order remained correct.
- Copy the complete current result or download it as a local TXT file.
Leave Separator empty when the lines should be concatenated with no characters between them.
Examples
Comma-separated names
Use , to turn a vertical name list into one readable comma-separated line.
Pipe-separated labels
Use | to prepare labels for a compact navigation, prompt, or plain-text summary.
Semicolon-separated values
Use ; when commas already appear inside the individual source lines.
Words joined with one space
Use a single space as the Separator to combine one-word lines into a sentence-like sequence.
Direct concatenation
Leave Separator empty to combine the lines directly, such as AlphaBetaGamma.
Skip blank lines
Empty and whitespace-only lines are omitted so they do not create duplicate separators or empty items.
Frequently asked questions
Does the tool change my original text?
No. The source remains in its original field while the joined artifact appears separately.
Are blank lines included?
No. Empty and whitespace-only lines are skipped and counted separately.
Are duplicate lines removed?
No. Every nonblank line remains in source order, including repeated values.
Are leading and trailing spaces inside lines preserved?
Yes. The content of each nonblank source line is joined exactly as entered. Only line breaks and skipped blank lines are removed.
Can the separator be empty?
Yes. An empty Separator directly concatenates all nonblank lines.
Can I use symbols such as pipes or slashes?
Yes. Symbols and spaces are treated as literal text and inserted only between joined items.
Does this create valid CSV?
Not necessarily. This tool performs literal joining and does not quote or escape commas, quotation marks, or line content according to CSV rules.
Can I use a line break as the separator?
No. This version uses a single-line Separator because its primary artifact is one continuous line.
Is my text uploaded?
No upload is performed by this tool. Joining, copying, and TXT generation run in the browser.
Why should I review the result?
Literal separators can create unintended punctuation or spacing, and preserved spaces inside source lines may affect the final output.
Method and limitations
The tool normalizes CRLF and CR source line endings to LF for analysis, then reads the source as an ordered sequence of logical lines.
Every line containing at least one non-whitespace character becomes an item. Empty and whitespace-only lines are excluded. The selected Separator is inserted exactly between items, never before the first item or after the final item.
The content and order of each nonblank line remain unchanged. Copy text and Download TXT resolve the current Source and Separator immediately before creating the artifact. The original source field is never overwritten automatically.
Limit: This version does not provide CSV-aware quoting, regular expressions, trimming, duplicate removal, sorting, numbering, multiline separators, semantic interpretation, file upload, or batch processing.
