How to flatten text to a single line

1. Paste multi-line text

   Put content with line breaks into the Text field. Both \n and \r\n endings are accepted.

2. Know what collapses

   Every line break becomes a single space; runs of whitespace (tabs, multiple spaces) collapse to one space; leading and trailing whitespace is trimmed.

3. Run the flatten

   Press Run. The output is one continuous line suitable for SMS, single-line form inputs, or a CSV cell.

4. Copy the result

   Copy the flattened text. If you need paragraph markers kept, insert a sentinel (e.g. " — ") with Find/Replace before running.
