Practical tip

Case-insensitive matching treats Apple and apple as the same item. By default the first matching line is preserved, keeping your original order unless you enable sorting.

Common questions

Will my original line order be preserved?

Yes, unless you enable alphabetical sorting. The first occurrence is retained.

Can I ignore capitalization and whitespace?

Yes. Enable case-insensitive matching and trim spaces to normalize comparisons.

Does PackFormulas keep my pasted lists?

No. The text is processed locally in the browser.
