Can I view Excel files without Microsoft Excel installed?

Yes! DocsYogi's Excel viewer works completely independently of Microsoft Excel. You don't need Excel, Office 365, or any Microsoft software. The viewer uses open-source SheetJS technology to render XLSX files directly in your browser, giving you full access to spreadsheet data on any device without software installation or licenses.

Is it safe to view confidential Excel spreadsheets?

Absolutely safe. Your Excel files are processed entirely in your browser using client-side JavaScript. Spreadsheets are never uploaded to our servers, stored in the cloud, or transmitted over the internet. This makes DocsYogi ideal for viewing confidential financial reports, business data, payroll information, sales figures, and sensitive business intelligence.

Can I view multiple sheets in one Excel file?

Yes! The viewer fully supports Excel workbooks with multiple worksheets. Sheet tabs appear at the bottom of the viewer, allowing you to navigate between different sheets instantly. Each sheet displays with its own data, formatting, and structure. Perfect for complex workbooks with organized data across multiple sheets.

Will formulas and calculations be displayed?

Yes, the viewer displays both cell formulas and their calculated results. You can see the underlying formulas (like =SUM(A1:A10)) and the computed values. This transparency helps verify calculations and understand spreadsheet logic. Formula syntax and cell references are preserved accurately.

What Excel file formats are supported?

The viewer supports modern XLSX files (Microsoft Excel 2007 and later) and older XLS files (Excel 97-2003). Both formats work perfectly with accurate rendering of data, formulas, and formatting. Files created in Microsoft Excel, Google Sheets (exported as XLSX), LibreOffice Calc, or other spreadsheet applications are fully compatible.

What is the maximum size for Excel files?

You can view Excel spreadsheets up to 50MB in size. This accommodates large datasets with thousands of rows, multiple worksheets, and complex workbooks. Most typical Excel files (reports, budgets, data sheets) are under 10MB and load quickly. Very large files may take a few seconds to process depending on your device's performance.

Can I edit the Excel spreadsheet?

No, this is a viewer-only tool designed for reading and analyzing Excel data. You cannot edit cells, modify formulas, or save changes. This ensures data integrity and prevents accidental modifications. If you need to edit, download the original file and open it in Microsoft Excel, Google Sheets, or another spreadsheet application.

Can I copy data from the spreadsheet?

Yes, you can select and copy cell data from the Excel viewer. Click and drag to select cells, then copy to your clipboard (Ctrl+C or Cmd+C). The copied data maintains cell structure and can be pasted into other spreadsheet applications, text editors, or documents. Perfect for extracting specific data, values, or ranges from Excel files.
