How to use Convert Newlines to Spaces
- 1. Paste the multi-line text. Enter the text with line breaks you want joined into the input pane, whether it is a few lines or a long multi-paragraph document.
- 2. Choose how to handle repeated breaks. Turn on Treat repeated breaks as one space to collapse consecutive blank lines into a single space instead of inserting one space per line break.
- 3. Copy the single-line result. Copy the joined text and paste it wherever a single unbroken line is needed, such as a CSV cell or a search query field.
When to use Convert Newlines to Spaces
Convert Newlines to Spaces replaces every line break in a string with a space, joining a multi-line block into one continuous line. It is the reverse of wrapping text, useful whenever downstream storage cannot handle embedded newlines.
- Preparing a value for a CSV cell. A multi-line address or comment needs to become a single CSV field, since embedded newlines can break naive CSV parsers or misalign rows when opened in a spreadsheet.
- Flattening a description for a database column. A product description was pasted with line breaks, but the target database field expects a single line of text without embedded newline characters.
- Cleaning up text copied from a PDF. Text copied from a PDF often has a line break after every visual line; joining them with spaces restores normal paragraph flow before pasting into an editor.
- Building a single-line log message. A multi-line error message needs to become one line so it doesn't break a log aggregator's line-based parsing when written to a log file.
