Filter Lines
Filter lines online by keeping or removing rows that contain specific text or match a regex pattern, all locally in your browser.
Use the result as the next input for sorting, deduping, joining, counting, or spreadsheet cleanup.
Filter lines workflow tips
Line filtering works best in the middle of a cleanup flow: normalize the source, filter rows, then sort, dedupe, count, or join the remaining lines.
Filter logs and exports
Keep only lines containing error, remove rows with old labels, or isolate email domains before sending the result to Line Counter.
Clean lists before filtering
Start with Trim Lines, Remove Tabs, or Normalize Whitespace when copied rows have uneven spacing.
Finish the filtered list
After filtering, use Remove Duplicate Lines, Sort Lines Alphabetically, or Join Text to prepare the final output.
Example filters
Use plain text such as @example.com to keep matching contact rows, or regex such as ^SKU- to keep product lines that start with a prefix. If you need to escape literal regex punctuation first, use the Regex Escape Tool.
What this tool does
Use this browser-only Filter Lines tool to clean pasted logs, keyword lists, exports, contact rows, labels, or copied text. Keep matching lines, remove matching lines, choose plain-text or regex matching, and copy the filtered result for the next cleanup step.
Common use cases
Keep or remove matching lines from pasted logs, lists, exports, labels, and text rows before sorting, deduping, counting, or joining the result.
Use Filter Lines when pasted text needs counting, cleanup, rewriting, list preparation, formatting, or a final check before it goes into an email, document, CMS, spreadsheet, prompt, or publishing workflow.
How to use it
- Paste the logs, lists, rows, exports, or text lines you want to filter.
- Enter the text or regex pattern to match, then choose whether to keep or remove matching lines.
- Optionally trim line edges and remove empty output lines before copying the filtered result.
Example workflow
Paste the text you need to count, clean, split, join, sort, or reformat. Review the word, character, line, sentence, paragraph, spacing, or list result, then copy the cleaned output into your document, spreadsheet, CMS, prompt, or editor.
Privacy note
Filter Lines runs locally in your browser. ClearUtils does not upload, store, fetch, log, or inspect your pasted text.
FAQ
Does Filter Lines upload my text?
No. Line filtering runs locally in your browser and does not upload, store, fetch, log, or inspect pasted text on ClearUtils servers.
Can I remove matching lines instead of keeping them?
Yes. Choose remove matching lines to drop rows containing your text or matching your regex pattern.
Can I use regular expressions?
Yes. Switch from plain text contains to regex match when you need advanced patterns. Use Regex Escape Tool first when punctuation should be treated literally.
