Empty Line Remover

When Empty Lines Cause Problems

Empty lines that are harmless in a word processor become silent errors the moment text enters a technical system. Common issues include:

• CSV imports — blank rows create null records in databases.
• Code files — excessive blank lines inflate file size and reduce readability.
• Email copy-paste — extra line breaks from forwarded emails create awkward spacing.
• Shell scripts — some line-by-line processors mishandle blank lines.

Combine With Other Cleaners

For fully sanitized text, use this tool alongside the Whitespace Cleaner (to strip extra spaces) and the Duplicate Highlighter (to remove repeated entries). Together, they handle virtually every data quality issue in plain text.

How to Use the Empty Line Remover

Paste your text and click Remove Empty Lines. Every line that is blank, or that contains only spaces or tabs, is deleted, and the remaining lines are joined together in their original order. Copy the result with Copy result when you are done.

A Worked Example

This text contains a blank line, a line with only spaces, and two blank lines in a row:

After cleaning you get three tightly packed lines: a, b, c.

What Is and Is Not Changed

• Only whole lines that look empty are removed. The text on the remaining lines, including spaces at the start or end, is left exactly as it was.
• Paragraph breaks disappear. If your text is prose that depends on blank lines between paragraphs, this tool will merge it into a solid block. Use it for lists, logs, data and code rather than for essays.
• If you only want to collapse several blank lines into one, this is not the right tool. It removes all of them.

Common Uses

• Cleaning data before import. Blank rows in a pasted CSV or in a list of IDs can cause errors in spreadsheets and databases.
• Compacting logs and notes. Text copied from chat apps or terminals often has an empty line between every entry.
• Reducing scattered code. Remove accidental gaps from a snippet before sharing it.

A Good Order for Cleaning

For messy copied text, a reliable sequence is: clean the spacing with the Whitespace Cleaner, remove blank lines here, then use the Duplicate Highlighter to drop repeated entries and the Line Sorter to put the list in order.
