About Text Merge Lines
Text Merge Lines joins the non-empty lines of your input into a single line using a separator you provide. It filters out blank lines (after trimming) and concatenates the remaining lines with the separator string, which defaults to a single space.
How to Use
1. Paste your multi-line text into the Input area. 2. Enter the Separator to place between merged lines (default is a single space). 3. Click the Merge button to produce the output. 4. Review the merged result in the Output area.
Separator Behavior and Empty Lines
The separator is inserted exactly as typed between every pair of surviving lines, so entering ", " yields "a, b, c" while entering "" (empty) yields "abc" with no gap. Blank lines are always removed before joining: a line is dropped when its trimmed content is empty, so consecutive blank lines collapse to nothing and never produce duplicate separators.
