What Are the Filter Modes?

Filter modes control how lines are matched and processed.
You can use simple keyword filtering or more advanced inclusion and exclusion logic.

• Remove matching lines: Deletes lines that match your criteria.
• Keep matching lines: Extracts only the lines you want.
• Multiple keywords: Match one or more terms at once.

Case Sensitive vs Case Insensitive — What’s the Difference?

Case sensitivity determines whether letter casing matters during filtering.
This affects how accurately lines are matched.

• Case Insensitive: Best for general text cleanup.
• Case Sensitive: Ideal for code, IDs, or exact matches.

How Do Advanced Rules Work?

Advanced rules give you precise control over filtering behavior.
Combine multiple conditions to target exactly the lines you want.

• Match any or all keywords (OR / AND logic).
• Exclude lines that contain specific terms.
• Trim whitespace before matching.
• Ignore empty lines automatically.

⚙️ Advanced Tip: Use multiple rules together to clean large datasets, logs, or exports efficiently.

What Are the Line Counts & Statistics?

After filtering, the tool displays clear statistics so you understand the impact of your rules.

• Input lines: Total number of original lines.
• Removed lines: Lines filtered out by your rules.
• Output lines: Final remaining or extracted lines.
