Câu hỏi thường gặp
Is the cong cu dem dong free?
Yes. The tool is free to use with no account, no download and no usage limit.
Is my text uploaded anywhere?
No. All counting happens locally in your browser, so your pasted text stays on your device.
Does it count blank lines?
Yes. The tool shows total lines, non-empty lines and blank lines separately, so you can decide which count matters for your task.
Does a trailing newline count as a line?
Yes. If your text ends with a line break, the counter treats the space after it as a final blank line.
Which line endings does it support?
It supports LF, CRLF and CR line endings. Windows, macOS, Linux and terminal output all count consistently.
Can I count lines in code or CSV data?
Yes. Paste code, logs, CSV, TSV or one-item-per-line lists. The tool treats the content as plain text and never uploads it.
