Frequently asked questions
Can CSV contain multiple worksheets?
No. A CSV file represents one flat table. Use an Excel workbook when you need several worksheets, formulas, charts or cell formatting.
Which format is better for system imports?
CSV is commonly preferred for straightforward bulk imports because it is simple and portable. Excel may be required when the receiving process depends on named sheets, formatting or formulas.
Will saving Excel as CSV preserve formulas?
No. CSV stores the displayed cell values rather than workbook formulas, formatting, comments or multiple sheets. Keep the original workbook as the editable source.
What should I verify before importing a CSV?
Check the delimiter, headers, character encoding, date format, decimal separator, leading zeros and quoted fields against the destination system's specification.
