Remove Lines Containing

The Remove Lines Containing utility is a lightning-fast way to strip unwanted lines from any text document. Enter the content, specify the word, phrase, or regular expression you want to eliminate, and the tool returns a cleaned version instantly.

Feature set

• Literal or regex matching: Choose between simple phrase matching or full regular expressions.
• Case control: Toggle case sensitivity when you only want to match exact casing.
• Whole-word guard: Keep matches precise by requiring word boundaries when regex is disabled.
• Live counters: See how many lines were matched and removed after every change.
• File uploads: Clean log files, CSV exports, or Markdown notes by uploading them directly.

Typical workflow

1. Paste or upload your text into the input panel.
2. Type the word/phrase (or regex) to match. Enable case-sensitive or regex mode as needed.
3. Watch the output panel update with the filtered result, and copy or download the cleaned text.
4. Use “Trim empty lines” if you want to collapse leftover blank space after removals.

Perfect for

• Filtering noisy log lines, stack traces, or debug messages before sharing them with teammates.
• Removing comments, metadata, or headings before feeding text into other tools or scripts.
• Cleaning CSV or TSV exports that contain header repeats or advertisement rows.
