Blank Line Counter
Count empty or whitespace-only lines in multiline text.
About this tool
Count empty or whitespace-only lines in multiline text. Enter a short sample or paste your own content, then review the result before using it elsewhere. The tool processes text locally in your browser and does not upload it. Character, line, and pattern rules are described on this page so the output is predictable. For accurate use, review the input format and sample shown here. Empty input produces an empty result or a zero count where appropriate. Numeric settings are validated before processing, and the original content remains unchanged so you can compare the generated result with the source before copying it.
How to use this tool
- Enter text in the labeled field.
- Set any requested option.
- Run the tool and review the result.
