CleanSheet CSV is a fast, no-fuss cleanup tool for messy spreadsheet data. Upload a CSV and CleanSheet deduplicates rows, trims stray whitespace, normalizes column headers, fixes inconsistent casing, and flags malformed rows before they break your imports. It is built for operators, marketers, bookkeepers, and small teams who receive CSV exports from CRMs, ad platforms, payment processors, and form tools, files that arrive with duplicate contacts, mixed date formats, and ragged columns. Instead of hand-editing in a spreadsheet for an hour, you get a clean, import-ready file in seconds, with a summary of everything that was changed so you can trust the result. No formulas to write, no macros to debug, no data leaves your workflow undocumented. CleanSheet CSV is part of the Mergify Digital product line: small, sharp tools that remove one recurring annoyance from a working day, priced once and yours to use. It turns a messy export into a file you can import with confidence.
