XLSX to CSV — Export Excel Data as CSV

CSV is the universal format for data exchange between applications, databases, and programming tools. The MyPDF XLSX to CSV converter extracts your Excel data into clean, portable CSV files.

How to Convert XLSX to CSV

1. Upload your XLSX file by dragging it onto the converter.
2. Configure the delimiter (comma, semicolon, or tab) and select which sheet to export.
3. Download your CSV file, ready for import into any database or application.

When to Use CSV

Use Case	Why CSV
Database imports	CSV is natively supported by MySQL, PostgreSQL, etc.
Data analysis	Python, R, and other tools read CSV directly
CRM uploads	Most CRM systems accept CSV for bulk imports
Data migration	CSV works as an intermediary between incompatible systems

Practical Tips

• Choose the right delimiter. Commas are standard, but if your data contains commas (like addresses), use semicolons or tabs to avoid parsing errors.
• Watch for encoding issues. If your spreadsheet contains accented characters or non-Latin text, ensure the CSV is exported as UTF-8.
• Handle multi-sheet workbooks. CSV only supports a single sheet per file. For multi-sheet workbooks, you will get one CSV per sheet.

Will formulas be converted?

CSV exports the calculated values, not the formulas themselves. If cell A1 contains =SUM(B1:B10), the CSV will contain the resulting number.

What happens to formatting?

CSV is a plain-text format, so all formatting (colors, fonts, borders, merged cells) is stripped. Only the raw data values are preserved.

Can I convert CSV back to XLSX?

Yes. Use MyPDF's CSV to XLSX converter to rebuild a formatted spreadsheet from your CSV data.
