Convert CSV data into a usable Excel workbook.
A CSV can look broken when delimiters, encoding, dates, or leading zeros are interpreted incorrectly. MessyFile converts one supported CSV into XLSX and checks that the worksheet dimensions and values remain usable.

- Header row and expected columns
- Row and column counts
- Delimiter handling
- Quoted values and embedded punctuation
- Character encoding problems
- Leading-zero, date, and long-number risks visible in the source
Important: CSV contains values, not Excel formatting, formulas, charts, or multiple worksheets. Features absent from the source cannot be recovered.
Questions
Can you preserve leading zeros?
Usually, when you identify the affected columns. Tell us which values must remain text.
Can you add formulas or redesign the workbook?
That is spreadsheet development, not a standard conversion, and requires a custom scope.
What if the CSV uses a semicolon?
Tell us the delimiter if known. Ambiguous files may need assessment.
