Filter Lines by Keyword keeps or removes lines based on matching words, phrases, or patterns. Use it to isolate log events, extract customer records, clean lists, or remove rows that include unwanted terms.
Filter Lines by Keyword processes text directly in your browser and returns a clean output plus practical statistics. The result card helps you confirm how many lines, items, matches, or characters were changed before you copy the result.
For very large pasted files, preview the output before replacing production data. Browser-based processing keeps the text local to the page.
Sample input: apple pie banana bread green apple orange juice
