SheetCleaner is a privacy-first browser tool for cleaning, merging, and deduplicating Excel and CSV files.
It supports multi-file and cross-sheet processing, multi-column duplicate keys, case and whitespace handling, regex extraction, and numeric tolerance. Users can keep records by order, date, minimum or maximum value, merge missing fields, or aggregate numeric data such as inventory quantities.
Duplicate groups can be reviewed before export. All file contents are processed locally in the browser and are never uploaded, making SheetCleaner suitable for customer lists, product catalogs, inventory files, and other sensitive spreadsheets.
Transform and standardize your CSV files with ease. Our powerful yet user-friendly platform makes data normalization accessible to everyone, saving you countless hours of manual formatting.
No more manual edits. Just fast, automated normalization.
