Blank Line Removal

When to Remove Blank Lines

Clean up copied text, configs, log output, and markdown drafts where extra vertical spacing makes processing harder. Lines that are empty or contain only whitespace are removed.

Real-World Examples

Compact log excerpts for email or ticket attachments

Prepare one-line-per-record input for line-based tools

Common Mistakes

  • Removing intentional paragraph breaks in prose — this tool removes all blank lines
  • Confusing with Whitespace Tools — use Trim to keep structure but clean edges
  • Expecting Windows \r\n handling issues — the tool normalizes line endings

Developer Tips

  • Run before Sort Lines or Dedupe Lines for cleaner input
  • Keep a copy of the original if you need paragraph spacing restored

Frequently asked questions

Are lines with only spaces removed?

Yes. Lines containing only whitespace (spaces, tabs) are treated as blank and removed.

Does this collapse multiple blank lines to one?

No. All blank lines are removed entirely. The result has no blank lines unless you add them back.

Will single-line text change?

Text without line breaks is unchanged. This tool operates on line boundaries.
