About SheetSanitizer

Spreadsheets often hide subtle errors that can disrupt data workflows, such as invisible characters, broken dates, or invalid email addresses. These issues are hard to spot just by looking, which makes manual cleaning tedious and error-prone.

SheetSanitizer tackles this problem by letting you upload any CSV or Excel file directly in your browser. It scans your spreadsheet to detect and highlight hidden problems like extra spaces, inconsistent date formats, and duplicates, helping you spot trouble spots immediately. Since the tool runs entirely in your browser, your data never leaves your computer, keeping your information secure.

This makes the process quick and private, avoiding the delays or risks of uploading files to servers. It’s a handy way to ensure your spreadsheet data is reliable before sharing or importing it elsewhere.
