What counts as an empty line?
The tool removes two types of lines: completely blank lines (no characters) and whitespace-only lines (lines that contain only spaces, tabs, or other invisible whitespace characters). Lines with any visible text are preserved.
Will this change my data formatting?
No, the tool only removes empty and whitespace-only lines. All remaining lines keep their original content, indentation, and formatting. The relative order of non-empty lines is preserved exactly as it was.
When is removing empty lines useful?
Common uses include: cleaning up copied text from PDFs that often adds extra blank lines, removing gaps from log files, compacting configuration files, cleaning data exports, and preparing text for import into databases that reject empty rows.
Does it handle different line endings?
Yes, the tool works with Windows (CRLF), Unix/Linux (LF), and Mac (CR) line endings. The output uses the same line ending style as your browser and operating system.
Common Use Cases
Empty lines can creep into text from many sources — PDF exports, email formatting, copy-paste artifacts, and generated output. Removing them manually is tedious and error-prone, especially in large documents.
