Spreadsheet conversion

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.

What we check

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.
