Frequently Asked Questions
What is the difference between keep matching items and remove matching items?
Keep matching items outputs only the lines that match your rules. Remove matching items sends matches to the Removed output and leaves the non-matching lines in Kept.
How do AND and OR work when I add multiple filter rules?
AND requires every rule to match for a line to be treated as a match. OR treats a line as a match if it satisfies at least one of the rules.
How does the length > n rule filter a list?
The length > n rule matches items whose character count is greater than n. This is useful for keeping or removing entries that are longer than a chosen threshold.
Why do Trim spaces and Case-insensitive options change my matches?
Trim spaces removes extra leading and trailing spaces before matching, preventing whitespace from affecting comparisons. Case-insensitive treats uppercase and lowercase as equivalent for text rules.
What happens when Ignore empty lines is enabled?
Ignore empty lines skips blank rows so they are not evaluated by the rules and do not appear in the outputs. This makes counts and results cleaner when the input contains extra line breaks.
