Join Lines with Delimiter converts a vertical list into one compact delimited string. Use it for CSV values, SQL IN clauses, JavaScript arrays, JSON arrays, email lists, tags, and clean copy-paste workflows.
Join Lines with Delimiter processes text directly in your browser and returns a clean output plus practical statistics. The result card helps you confirm how many lines, items, matches, or characters were changed before you copy the result.
For very large pasted files, preview the output before replacing production data. Browser-based processing keeps the text local to the page.
Sample input: Apple Banana Orange Pear
The tool uses line-based or delimiter-based parsing depending on the selected mode. It preserves original item order unless sorting is enabled, and it keeps duplicate values unless deduplication is enabled.
Complex quoted CSV, nested delimiters, or malformed regular expressions may require a dedicated CSV or regex tool. Always review output for high-stakes data.
Choose Comma list and run the tool. Each non-empty line is joined with commas.
