Compare Two Lists FAQ

Is this tool private?

Yes. The comparison runs in your browser, so the list content does not need to be uploaded to a server for processing.

Can I compare messy copied text from Excel?

Yes. The delimiter and normalization controls are built for pasted spreadsheet values, CSV exports, and plain text lists.

What do fuzzy matches do?

They help spot near matches such as singular versus plural forms, typos, and small wording changes between two lists.

Will this site stay fast as more tools are added?

That is the goal. Each tool should remain on its own page, with reusable layout pieces and only the JavaScript it needs.
