About Remove Line Breaks
The Remove Line Breaks tool joins multiple lines into a single line using any separator you choose — space, comma, semicolon, pipe, or custom text. Empty lines are filtered out automatically so you do not get double separators.
Common use cases include converting vertical lists into comma-separated strings, cleaning text pasted from PDFs and emails, joining SQL values, merging log lines, and preparing data for CSV fields.
The separator field accepts any string — single characters like `,`, `;`, or `|`, multi-character sequences like `, ` (comma-space) or ` → `, or even nothing (empty string) to concatenate lines with no gap. This makes it straightforward to build SQL IN clauses (`'val1', 'val2', 'val3'`), join Markdown list items into inline text, or format comma-delimited API parameters. All processing runs locally — your text never leaves your browser.
Frequently Asked Questions
Can I use a comma as the separator?
Yes. Type any character or string into the 'Join with' field — comma, semicolon, pipe (|), tab, or even a multi-character phrase.
Are empty lines removed?
Yes. Blank lines are filtered out before joining so you do not get double separators or extra spacing in the output.
Can I convert a list into a comma-separated string?
Yes. Paste your list (one item per line), set the separator to ', ' (comma-space), and click Remove Line Breaks. You get a clean CSV-style string.
Does it preserve spaces within lines?
Yes. Only line break characters are removed. Spaces and other whitespace within each line remain exactly as they are.
Is my text sent to any server?
No. All processing happens locally in your browser. Your text never leaves your device.
