Spreadsheet Viewing Without Excel
Microsoft Excel and other spreadsheet applications create files that require specific software to open. Our browser-based viewers parse XLSX, XLS, and CSV files using JavaScript, rendering data in interactive tables without any installation.
Multi-Sheet Workbooks
Excel files often contain multiple worksheets—separate tables within one file. Our viewer displays tabs for each sheet, letting you switch between them just like in Excel. See all your data without the original application.
Data Exploration
Search and filter data across large spreadsheets. Copy individual cells or entire ranges. View cell formulas and formatting. Export sheets as CSV or HTML for use in other tools.
Format Support
Modern XLSX files (Excel 2007+) use an XML-based format that's easily parsed in browsers. Legacy XLS files (Excel 97-2003) use a binary format with limited browser support. CSV files are plain text and work universally.
Common Use Cases

- Quick inspection: Check contents before opening in desktop software
- Cross-platform access: View Excel files on devices without Office licenses
Privacy Benefits
Spreadsheets often contain sensitive financial data, customer lists, or confidential business information. Our viewer processes files entirely in your browser using SheetJS—no data is uploaded to servers, ensuring complete privacy.
