Privacy details

Remove lines containing text processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Using Remove lines containing text

Enter the text to find and remove each line that contains it. Switch to “Keep matching lines” to extract matching rows instead. The original content of retained lines is preserved.

Matching is a literal substring search. Searching cat also matches catalog; punctuation such as dots and brackets is ordinary text, not a regular expression.

A worked example

With cat as the match, “cat: feed tonight” is removed and “dog: walk today” remains.

Before you use the result

This filters whole lines and does not replace individual matches. Case-insensitive matching uses English lowercase rules; it does not normalize accents or infer equivalent spellings.
