How it works

Stop manually checking rows in Excel. Upload your CSV here, and our AI will detect exact duplicates, fuzzy matches, and inconsistent data entries in seconds.

DataDigger processes your file entirely in memory. Whether you are looking to clean up a mailing list, audit financial records, or just make sense of a raw database dump, our flexible discovery engine does the heavy lifting for you.
