Identifiers remain text, including leading zeros. Duplicate IDs are marked ambiguous, rather than automatically paired. No rows are silently removed. You choose which fields to compare.
Clear limits.
Each file can contain up to 5 MB, 50,000 rows, 200 columns, and 1 million cells. Detail exports stop at 5,000 findings and disclose truncation; summary counts remain complete.
Local data handling.
The downloaded app uses no network services. Files are held for the current browser session and cleared when you clear them or close the page. Store your exported reports securely.
A focused tool.
This version supports UTF-8 comma, semicolon, and tab-delimited files. It does not parse Excel workbooks, perform fuzzy matching, or make changes to your business systems.
