How It Works
The Join Lines tool merges all lines of your text into a single line, separated by the string you specify. The default separator is a comma followed by a space (, ), which is ideal for creating comma-separated lists from line-separated data.
Options include:
- Skip empty lines — Ignores blank lines during the join, preventing double separators.
- Trim whitespace — Removes leading and trailing spaces from each line before joining.
This is the inverse of the Split Text tool. Common use cases include converting a list of items into a comma-separated string, combining log entries, or preparing data for CSV export. All processing runs entirely in your browser. No data is transmitted to any server.
