How to use Convert Newlines to Spaces
- 1. Paste your multi-line text. Enter the list or block of text with values on separate lines into the input pane, such as a list of words or short entries.
- 2. Choose whether to collapse repeated breaks. Turn on Treat repeated breaks as one space so multiple consecutive blank lines produce a single space instead of several, avoiding extra gaps in the joined result.
- 3. Copy the single-line result. Copy the joined text from the output pane, where every line break has become a space, producing one continuous space-separated line.
When to use Convert Newlines to Spaces
Convert Newlines to Spaces replaces every line break with a space, joining multi-line text into one continuous line. Use it whenever a list of one-per-line values needs to become a single space-separated string.
- Turning a word list into a sentence. You have a list of words, one per line, and want them joined into a single space-separated line to paste into a sentence or search query.
- Preparing tags for a single-line field. A list of tags currently sits one per line, but the destination field expects them space-separated on a single line. Join them here before pasting.
- Flattening a multi-line command for one-line use. You have a command or script written across several lines for readability but need to run it as a single line in a terminal that expects one command per line.
