About this app

CellMender CSV Normalizer turns awkward tables into clean, portable files without sending your data anywhere. Open CSV, TXT, TSV, Markdown or Excel workbooks; inspect a clear preview; and export to XLSX, UTF-8 CSV, tab-delimited TXT or Markdown. CellMender detects common encodings and separators, respects quoted fields and embedded line breaks, repairs frequent text-encoding damage only when the result improves, and pads uneven rows without rewriting your source values. All processing happens locally. There are no accounts, ads, analytics, cloud APIs or uploads.
