How do you use the count lines tool?
- 1. Add your text. Paste it directly, upload a file, or drop a TXT/CSV/JSON file onto the input box.
- 2. Adjust the options. Use the controls above the editor to fine-tune how the tool behaves.
- 3. Copy or download the result. Your cleaned text is ready instantly, with nothing ever sent to a server.
Need to remove duplicate lines too? Try the full Text Dedupe, which adds case-insensitive matching, consecutive-only mode, sorting, and large-file support.
