Exact: Matches whole words only (e.g., “cat” won’t match “category”). Partial: Matches anywhere in line (e.g., “cat” matches “category”). Regex: Use powerful patterns like \d{3} for 3 digits.
Yes! Check “Keep Lines Containing Words (Invert)” to flip the behavior — only lines with your keywords will remain. Great for extracting specific entries.
By default, it’s case-insensitive. Check “Case Sensitive” if you want “Apple” and “apple” treated differently. Works with all matching modes including regex.

Paste the source text, apply the transformation, inspect the changed text, and copy the result only after checking punctuation, spacing and meaning.
Preview or keep a copy of the original before destructive changes so you can recover information if the wrong item is removed. Automated text transformations can change formatting or context. Keep the source text when exact wording matters.
Expected: Transformed text that applies the requested rule consistently to the supplied input. Avoid: Overwriting the only copy of the source before checking punctuation, whitespace and edge cases.
Text transformations are easiest to trust when you can compare the result with a small sample first. Use Remove Line With Matching Word on representative text, confirm that punctuation, whitespace, markup or character encoding behaves the way you expect, and only then process larger blocks. Keep a copy of the source when wording or structure matters, because some transformations are intentionally destructive or difficult to reverse exactly. For structured text or markup, test the result in its destination as well so syntax and escaping still behave as intended.
