What Is a CSV File?
CSV stands for "comma-separated values." It's a simple text format where each row is a line and each value is separated by a comma. As it's so lightweight and universal, CSV is the format most tools ask for when you import contacts, products, records, or reports. Converting Excel to CSV strips out the extra spreadsheet formatting and leaves just the raw data - exactly what those tools need.
How to Convert Excel to CSV
You can convert an Excel file to CSV in three quick steps:
- Open our Excel to CSV converter and upload your XLSX or XLS file.
- Click Convert to start the Excel to CSV conversion.
- Download your CSV file, ready to open or import anywhere.
That's it, no formulas to rewrite and no formatting to clean up afterward.
Why Convert Excel to CSV?
Excel files carry a lot of extra baggage - styles, formulas, multiple sheets, and formatting that many systems can't read. A CSV keeps only the data, so it uploads cleanly and works almost everywhere. Here's when converting Excel to CSV helps most:
- Importing data - most CRMs, email tools, and databases accept CSV, not XLSX.
- Sharing raw data - send a clean file without formulas or hidden formatting.
- Working with code - CSV is the go-to format for scripts, data analysis, and bulk uploads.
- Cutting file size - a CSV is far smaller than the same data in Excel.
