Quick Start
- Open the Remove Empty Lines tool on HeronTool.
- Paste the text you want to clean into the input box (or upload a file).
- Choose a cleaning mode: remove only completely empty lines, remove lines containing only whitespace, or also trim leading/trailing whitespace.
- Click the "Process" button to see the result preview on the right.
- Once satisfied, click "Copy Result" or "Download" to save the cleaned text.
Advanced Options
- Smart Dedup: If your text also contains duplicate lines, first use the Text Deduplicator tool, then remove empty lines to avoid missing any.
- Batch Processing: HeronTool supports multi-file upload, handling multiple text files at once to save time.
- Custom Rules: You can define what counts as a "blank line" (e.g., lines with only spaces or tabs) to suit special formatting needs.
