Quick Fact

CSV files are the universal language of data. They can be opened by any spreadsheet software, text editor, or database importer.

Engineering Philosophy

Clean Data. UTF-8 Support.
Powered by Pandas.

Converting Excel to CSV seems simple until you encounter dates that turn into serial numbers, special characters that break encoding (like Bengali or Emojis), or merged cells that ruin the structure.

We use Python's Pandas library—the gold standard in data science—to handle your files. It intelligently parses types, formats dates correctly, and ensures every cell is preserved exactly as meant to be interpreted by machines.

We also enforce UTF-8 encoding on all outputs, ensuring your data is ready for modern web apps, SQL databases, and data pipelines without character corruption.

Built for Data Integrity

Clean comma-separated values ready for databases.

UTF-8 Ready

Supports all languages, emojis, and symbols.

Multi-Sheet Support

Each sheet becomes a separate CSV file automatically.

Why Use CSV format?

Excel files (.xlsx) are great for human viewing with their formatting, colors, and formulas. But when you need to feed data into a system, import it into a database, or analyze it with code, they can be heavy and complex.

CSV (Comma Separated Values) strips away the visual noise. It's a plain text format where data is separated by commas. It is light, fast, and supported by virtually every data tool in existence.

Key Terminology

Delimiter

The character that separates values. In CSV, it's a comma (,), but sometimes semicolons (;) are used in Europe.

Encoding

How python translates bytes to characters. We use UTF-8 to support all languages.

Workbook vs Sheet

An Excel file is a Workbook that can contain multiple Sheets. A CSV file represents only one Sheet.

Pandas DataFrame

The robust internal data structure we use to hold your data during conversion.

Tips for Best Results

  • Unmerge Cells: Merged cells can confuse data parsers. It's best to unmerge everything before converting.
  • Consistency: Ensure each column contains only one type of data (e.g., don't mix text in a date column).
  • Remove Headers: If you have title rows above your actual column headers, remove them so the first row is your header.

Common Questions

How are multiple sheets handled?
Since a CSV file can only contain one table, if your Excel file has multiple sheets, we automatically create a ZIP file containing a separate CSV for each sheet.
What happens to formulas?
The converter extracts the calculated values (the result of the formula) rather than the formula itself, which is exactly what you want for data export.
Does it support non-English characters?
Yes! We use UTF-8 encoding by default, so characters from any language (Bengali, Chinese, Arabic, etc.) as well as emojis are preserved perfectly.
Is my data secure?
Absolutely. We treat data privacy seriously. Files are deleted immediately after processing and never stored permanently.
