Filter Lines
Filter lines of a text or list that contain (or do not contain) a term. Supports regex and case-insensitive option.
How to use?
Paste your text in the input field and tell it which filter to apply. You decide whether to keep the lines that contain the searched term or, on the contrary, the ones that don't. For trickier patterns, switch on the regex option.
Filter a text's lines
In a large list, finding only the lines that matter (the ones with a word, or precisely the ones without it) is a job for a filter, not for line-by-line reading. You point to a term and the page pulls out, from the whole text, just what fits the criterion.
Once you type the term, you choose whether to keep the lines that contain it or the ones that don't. There's regular-expression support for more elaborate searches and an option to ignore capitalisation. It's quite a resource for sifting through logs, pulling specific records from a list or trimming data down.
The processing runs in the browser and the text isn't sent anywhere. Paste the list, adjust the filter and copy the resulting lines right after.
