Import Excel or CSV
Click or drag your workbook here. We'll parse it instantly.
Privacy First Data Transformation
Spreadsheets often contain sensitive financial or personal data. unlike traditional converters that upload your files to a server, our tool processes the workbook entirely in your browser's memory using the SheetJS engine. Your files never leave your device.
Seamless Data Ingestion
Modern application development often requires importing legacy spreadsheet data. Our converter simplifies this workflow by providing a structured JSON representation of your Excel and CSV files without the need for complex backend integrations.
Multi-Sheet
Detects all tabs within a workbook and allows you to toggle and convert them individually.
CSV Support
Native parsing for Comma Separated Values, the world's most common data interchange format.
Developer Ready
Outputs clean, pretty-printed JSON that is ready to be dropped into your codebase or API.
Enterprise Grade Privacy
Data breaches often start with "convenience" tools that
move information into the cloud. By executing the SheetJS engine directly in your browser's V8 thread, we eliminate
the need for any cloud upload. Your corporate files stay protected
by your local system's security.
