Every SEO and marketer ends up managing large lists of keywords, URLs, or text, and knowing how to quickly remove any line that begins with a specific character or text string is one of those small, repetitive tasks that quietly eats up time when it's done by hand.
What This Tool Actually Does
Remove Lines Starting With removes any line that begins with a specific character or text string, applied instantly to an entire pasted list at once.
Filtering Out a Specific URL Prefix
A crawl export mixing several subdomains can be filtered down by removing every line starting with a subdomain you don't need for the current task.
Why Doing This by Hand Doesn't Scale
Handling this manually is manageable for a handful of lines, but the moment a list grows to hundreds or thousands of entries, manual editing becomes slow and genuinely error-prone. A dedicated tool applies the same rule consistently across the entire list in seconds.
Next step: Use the free Remove Lines Starting With tool from SeoWolf's Notepad to remove any line that begins with a specific character or text string directly in your browser, with no login or software install required.
