FAQ
Questions about this tool
Can I combine AND and OR?
Yes. Conditions are grouped explicitly and the preview updates before export.
Can I remove matching rows instead of keeping them?
Yes. The same rule group can keep or exclude matches.
Are regular expressions supported?
Yes, with safety limits; invalid or risky expressions return a clear error.
