CSV to Excel
Open messy CSV files as a properly typed .xlsx workbook.
Turn a raw CSV into a formatted Excel workbook with detected headers, real dates and numbers, frozen panes and auto-sized columns. Delimiter and encoding are sniffed automatically, so semicolon files from European systems just work.

Common problems and fixes
Everything lands in column A.
The delimiter was mis-detected, usually because the header row uses a different separator than the body. Override it manually in the options panel.
Product codes like 00123 become 123.
Turn off auto-typing for that column in the preview grid, or enable “Treat all values as text”.
