Remove Line Breaks
Remove Line Breaks normalizes CRLF to LF, splits on LF, and joins every resulting line with one space. Existing spaces at line edges are not trimmed, so boundaries can produce multiple spaces; blank lines contribute additional spaces. A lone carriage return is not an LF boundary. This is textual joining, not paragraph reflow, hyphen repair, or sentence-aware spacing.
Runs locally — files stay on your deviceAre repeated spaces collapsed afterward?
No.
Joining boundaries can create new spacing artifacts
Replacing a line break with a space preserves neither exact source bytes nor typographic paragraph semantics.
How it works
The shared line splitter handles CRLF/LF and Array.join(' ') creates output.
Key concepts
Every boundary gets a space
Blank lines become additional spaces.
Edge spaces remain
A line ending in a space can create doubles.
When to use it
- Turn a clean one-item-per-line list into one line.
- Flatten copied wrapped text before further cleanup.
- Replace simple line boundaries with spaces.
When not to use it
- Do not expect paragraph meaning retained.
- Do not expect hyphenated line-wrap repair.
- Do not expect whitespace normalization.
Worked examples
Simple
- Input
a\nb- Expected output
a b
One boundary.
Blank line
- Input
a\n\nb- Expected output
a b
Two boundaries create two spaces.
Existing edge
- Input
a \nb- Expected output
a b
Existing space remains.
Common mistakes
Expecting normalized text
Multiple spaces can remain. Correction: Run Normalize Whitespace if desired.
Flattening paragraphs
Structure disappears. Correction: Preserve paragraph markers first.
Fixing PDF wraps blindly
Hyphens may need semantic repair. Correction: Review words and sentences.
Best practices
- Keep an original.
- Inspect blank-line boundaries.
- Normalize spaces only when appropriate.
