What this site provides
The site offers practical spreadsheet utilities for people who need quick file operations without installing desktop software or creating an account. The tools support common Excel and CSV workflows such as comparing two workbooks, merging files, splitting data by a column, converting formats, finding duplicates, and batch cleaning messy data.
Browser-side processing
Excel and CSV files are read by JavaScript in your browser using SheetJS. The Flask backend serves pages, translations, static files, and SEO routes; it does not process uploaded spreadsheets for the public tools. Your spreadsheet content stays on your device unless you choose to share it elsewhere.
