What Is a Line Filter?

A line filter keeps or removes lines from a text block based on whether they contain a specified keyword or match a regular expression pattern. It's essentially a browser-based `grep`, returning only the lines relevant to your search.

This is invaluable for working with large log files, configuration exports, or data dumps where you need to isolate specific entries without opening a terminal or writing a script.

How to Filter Text Lines

1. Paste multi-line text into the input area
2. Enter filter criteria: contains text, starts with, matches pattern
3. Choose include or exclude matching lines
4. Copy the filtered results

Features

• Filter lines by text content, prefix, or suffix
• Support for regular expression patterns
• Include or exclude matching lines
• Case-sensitive or case-insensitive filtering

Common Use Cases

• Extracting error lines from a long server or application log
• Isolating config entries that match a specific key prefix
• Filtering a CSV export to rows that contain a particular value

Why Use ToolPop Line Filter

• Filter lines by keyword or full regex pattern
• Include or exclude matching lines — both modes available
• Case-insensitive option for flexible pattern matching

ToolPop vs grep Command

The grep command is powerful but requires terminal access and knowledge of its flags. ToolPop provides the same line-filtering capability in a browser interface — accessible to anyone, with a visual result you can copy without any shell knowledge required.

Tips

• Filter log files to find specific errors or events
• Extract lines containing specific keywords from documents
• Remove unwanted entries from lists based on criteria

Frequently Asked Questions

Can I use regex patterns for filtering?

Yes. You can switch to regex mode and use complex patterns like '^ERROR' to match lines starting with ERROR.

Can I apply multiple filters at once?

You can combine filters with AND/OR logic, allowing you to create complex filtering rules.

Is filtering done locally without uploading my text?

Yes. All filtering happens entirely in your browser without involving any external servers.
