SUGUDASU Full-width/half-width normalization

Organize customer lists in-browser without using suspicious conversion sites.

OK even if conversion sites are prohibited by company policy. Clean up full-width/half-width characters, spaces, and line breaks in Excel columns within the browser only—input content is never sent to the server. Supports up to 500 rows with row count verification.

What you can do:

• Preset formatting for Excel columns by use case (full-width/half-width characters, spaces, line breaks, etc.)
• Display input N rows → output M rows before copying
• List organization, masking, date standardization, SQL IN clauses / tab-to-comma conversions and other list formatting
• Up to 500 rows • No registration required • Browser-based • Data never sent
