What is Excel to CSV conversion?
Excel files (.xlsx, .xls) contain rich spreadsheet data with formatting, formulas, and multiple sheets. Converting to CSV extracts the raw tabular data into a simple, universally-compatible text format that works with any data tool, database, or programming language.
When to convert?
Convert Excel to CSV when you need a universal text format for data import, when working with command-line tools, when preparing data for database imports, or when you need a lightweight format without Excel's overhead.
Frequently asked questions
Is my data safe when converting Excel to CSV?
Yes. The conversion runs entirely in your browser. Your Excel file is never uploaded to any server.
Which Excel formats are supported?
Both .xlsx (Excel 2007+) and .xls (legacy Excel) formats are supported.
What happens with multiple sheets?
The converter processes the first sheet of the workbook. Each sheet's data is converted to CSV format.
Does it handle formulas?
The converter extracts the calculated values, not the formulas themselves. What you see in the cells is what gets exported to CSV.
