DataSort
Clean, merge, and dedupe messy Excel files in your browser
About DataSort
Most Excel cleaners make you select the columns and hope. DataSort reads the file the way a person would: it finds the real header row buried under junk rows, catches fuzzy duplicates ("Jon Smith" vs "John Smith") rather than only exact matches, and merges files whose columns are named differently by mapping them itself. No install and no signup to try. Files are processed in memory and never stored. The free plan handles files up to 500 rows.
