Spreadsheets are a critical part of business operations—whether you’re tracking budgets, planning marketing campaigns, or evaluating complex datasets. But sharing .xls and .xlsx files isn’t always simple, especially when your recipient doesn’t have Microsoft Excel installed.

That’s where Doconut.app steps in. Our browser-based Excel Viewer allows you to upload and view spreadsheets instantly, without needing to install any software. It’s the perfect solution for teams who need quick insights, clean presentation, and easy sharing of financial or data-heavy documents.

Whether your spreadsheet includes multiple sheets, pivot tables, formulas, or embedded charts, Doconut.app preserves the structure and formatting. You can explore the data just as you would in Excel, with accurate cell rendering, styles, and layout positioning—right in your browser.

This is especially useful for project managers, accountants, analysts, and remote collaborators who need access to spreadsheets on any device. Our cloud-based platform is compatible with both .xls (legacy Excel) and .xlsx (modern Excel) file formats, so you can focus on analysis rather than troubleshooting.

Data security is at the core of our service. Files are encrypted during upload and removed shortly after your session ends, ensuring sensitive financial or operational data never stays on our servers.

Want to try it? Head over to Doconut.app and upload any .xlsx or .xls file. In just a few seconds, you’ll have a fully rendered, scrollable, and zoomable spreadsheet at your fingertips—accessible from any device with a modern web browser.

From Excel to Word, PowerPoint to Visio, Doconut.app gives you the power to preview, share, and review your files from anywhere. Experience a simpler, smarter way to work with documents—no software required.
