Delete every line that contains a specific word, phrase or regex pattern. Or invert it — keep only lines that match. Instant results.
This tool filters text line by line, removing (or keeping) every line that contains your specified keyword, phrase or regex pattern. It's the browser equivalent of the Unix grep -v command — filter out unwanted lines from a list, log file, or data export in seconds.
Removing error lines from a log file export. Filtering out comment lines that start with # from a config file. Deleting blank keyword entries from a list. Removing lines that contain certain domains from a URL list. Keeping only lines that match a specific pattern (use "Keep only matching lines" mode). Extracting lines that contain email addresses, URLs or numbers from mixed text.
Enable "Use regex" to unlock pattern-based filtering. For example: ^\d matches lines starting with a number, https?:// matches lines with URLs, (error|warning|critical) matches lines with any of three keywords.
