Remove Empty Lines
Strip blank lines from text. Remove all empty lines or collapse consecutive blanks to a single line. Optionally trim whitespace-only lines.
When to Clean Blank Lines
Extra blank lines creep into text when copying from websites, pasting from emails, exporting from databases, or working with code that has inconsistent formatting. This tool strips them out instantly, leaving you with clean, compact text. It is especially useful for cleaning up code, tidying pasted data before importing into a spreadsheet, and preparing documents for consistent formatting.
You can choose between two modes: remove all empty lines (eliminates every blank line) or collapse consecutive blank lines into a single one (preserves paragraph spacing while removing excessive gaps). Both modes can optionally treat whitespace-only lines as empty.
Collapse vs Remove
Removing all empty lines produces a solid block of text with no gaps, which is ideal for data processing, log cleanup, and creating compact lists. Collapsing reduces multiple consecutive blank lines down to one, which maintains readability and paragraph structure while eliminating ugly triple or quadruple spacing.
The whitespace-only option is important because lines that look empty may actually contain spaces or tabs. With this option enabled, lines containing only whitespace characters are treated as blank and cleaned up along with truly empty lines.
Frequently Asked Questions
What is a whitespace-only line?
A whitespace-only line looks empty but contains invisible characters like spaces or tabs. These often appear when copying text from websites or formatted documents. The tool can detect and treat these as empty lines when the whitespace-only option is enabled.
Should I collapse or remove blank lines?
Use collapse when you want to preserve paragraph breaks but eliminate excessive spacing, such as cleaning up a document or email. Use remove when you need compact output with no gaps at all, such as preparing data for import or cleaning log files.
Can I clean up code formatting with this?
Yes. Developers commonly use it to remove excessive blank lines from code files. The collapse mode is usually best for code, as it maintains separation between functions and blocks while removing unnecessary extra gaps.
