Why use our Excel-to-CSV converter?
CSV is the universal format for data portability. When you need to import spreadsheet data into a database, feed it to a script, upload it to a CRM, or share it with a system that does not support Excel, converting to CSV is the solution. Our tool extracts clean, properly formatted CSV from any Excel workbook — including files with complex formatting that would cause issues with a simple copy-paste.
Going the other way? Our CSV to Excel converter handles that. If you need to transform your data into JSON for an API or web application, try the JSON and CSV converter. You can also convert your spreadsheet data into a formatted document using our text to PDF tool.
What is an Excel file?
An Excel file (.xlsx or the older .xls format) is a spreadsheet document created by Microsoft Excel, one of the most widely used business software applications in the world. Excel files can contain multiple worksheets, formulas, charts, formatting, pivot tables, and macros. The modern .xlsx format is based on Open XML, making it compatible with many applications beyond Microsoft Office, including Google Sheets and LibreOffice Calc.
