Frequently Asked Questions
Why convert Excel to CSV?
CSV is a universal plain-text format that works everywhere. Convert Excel to CSV for: data imports/exports, database loading, programming (Python, R), compatibility with any tool, and handling files larger than Excel's 1M row limit.
Will formulas be preserved?
CSV stores values only, not formulas. When you convert Excel to CSV, formulas are calculated and their results are saved as plain values. This is perfect for data export and interchange.
What happens to multiple sheets?
Each Excel sheet is converted to a separate CSV file. For example, if you have 'Sales.xlsx' with 3 sheets, you'll get 'Sheet1.csv', 'Sheet2.csv', and 'Sheet3.csv'. You can also choose to convert specific sheets only.
Can I batch convert multiple Excel files?
Yes! Select entire folders and convert hundreds of Excel workbooks to CSV in one operation. Each sheet becomes a separate CSV file. Perfect for migrating data or automating workflows.
Will special characters be preserved?
Yes! Diwadi uses UTF-8 encoding by default, which preserves all special characters, international characters, emojis, and symbols. You can also choose custom encodings if needed.
Why use desktop converter vs Excel's 'Save As'?
Diwadi is faster for batch conversions, handles files larger than Excel's limits, preserves encoding perfectly, works on all sheets at once, and doesn't require Excel to be installed. Perfect for automating workflows.
Is Excel to CSV conversion free?
Completely free with unlimited conversions. No file size limits, no watermarks, no credit card required.
What's the difference between CSV and Excel?
Excel (XLSX) supports formulas, formatting, charts, and multiple sheets. CSV is plain text - simpler, smaller, universal. Convert to CSV when you need compatibility, data export, or to work with programming languages.
