Convert Excel to CSV

No. CSV can hold only one flat table and has no concept of multiple worksheets. If the workbook has several sheets, choose the worksheet you need or export them separately. Do not expect one CSV file to preserve the workbook's tab structure.

The CSV contains the computed values, not working spreadsheet formulas. CSV stores plain field values separated by delimiters, so formulas, cell formatting, charts, and workbook logic are outside the format. Keep the Excel file when you need calculations to remain live.

CSV does not store a strong cell type for dates, so the application opening it may interpret date-like strings using its own regional rules. Import the file with explicit column settings when exact date formats or identifier-like values must remain unchanged.

Yes. CSV is designed for broad data interchange and can be opened by spreadsheets, databases, scripts, and many import tools. Check the delimiter and character encoding expected by the receiving system, because those choices determine whether columns and non-English characters are read correctly.

Use CSV when the next system wants a simple table rather than a full workbook. It removes formulas, styling, charts, and extra worksheets, which is a limitation for collaboration but an advantage for imports, scripts, databases, and systems that only accept delimited data.
