How to Remove Line Breaks From Text
The line break remover joins multi-line text into a single block, replacing newlines with whatever separator you choose. It is especially useful for converting vertical lists into comma-separated values, combining addresses, or preparing text for databases or APIs that expect single-line strings.
Step 1: Choose your mode
Use "Remove Line Breaks" to join lines together (the default). Switch to "Add Line Breaks" to do the reverse — split a single-line text back into multiple lines at a separator character.
Step 2: Select a separator
Choose how lines are joined: a space (most natural for prose), a comma (CSV format), a semicolon (SQL-friendly), a pipe character, or a custom separator. The custom option accepts any text, including multi-character sequences like " | " or " — ".
Step 3: Handle whitespace and empty lines
"Trim each line" removes leading and trailing spaces from every line before joining — recommended when your text has inconsistent spacing. "Remove empty lines first" skips blank lines so they don't create extra separators in the output.
Common use cases
Convert a vertical list of IDs into a comma-separated list for a SQL WHERE id IN (...) clause. Join multi-line address fields into a single address string. Combine a list of keywords into a space-separated string for meta tag generation. Flatten multi-line copy-pasted text into a single line for embedding in a JSON field.
FAQ
What separators can I use when joining lines?
Choose from space, comma, semicolon, or a custom separator. Select 'Custom' from the dropdown and enter any text in the custom separator field — it can be multiple characters, a symbol, or even a word like ' | '.
Does it handle Windows line endings (CRLF)?
Yes. The tool recognizes both Windows (\r\n) and Unix (\n) line endings and removes them correctly. You don't need to pre-convert your text.
What does 'Trim each line' do?
It strips leading and trailing whitespace from each line before joining. This prevents extra spaces when lines have trailing spaces or inconsistent indentation.
What does 'Remove empty lines first' do?
Before joining, it filters out any blank lines so they don't produce double separators in the output. For example, two lines with a blank between them become two joined items, not three.
Is this tool free?
Yes, completely free. All processing runs in your browser — nothing is uploaded to any server.
Can I reverse the operation — split text back into lines?
Yes. Click 'Add Line Breaks' mode button at the top. This splits text at the separator and puts each piece on its own line — the reverse of the join operation.
What is the typical use for joining lines?
Common uses: combining a vertical list into a comma-separated string for SQL IN clauses, joining multi-line addresses into one line, or converting a list of keywords into a single space-separated string.
