Frequently Asked Questions (FAQ)

Is Excel Master Pro really completely free to use?

Yes, Excel Master Pro is completely free with no hidden costs, registration requirements, or usage limits. We believe in providing powerful tools accessible to everyone regardless of budget. The tool is supported through optional donations and premium support services, but the core functionality remains free forever.

How is my data protected when using Excel Master Pro?

Your privacy and data security are our highest priorities. Excel Master Pro processes all data locally in your browser using JavaScript - your files never leave your computer or get uploaded to any server. This approach ensures complete data confidentiality while providing powerful spreadsheet functionality.

What file formats does Excel Master Pro support?

Excel Master Pro supports both CSV (Comma Separated Values) and XLSX (Microsoft Excel) file formats for both import and export. This covers the vast majority of spreadsheet files used today. The tool uses the SheetJS library for robust file format handling, ensuring compatibility with files created in various versions of Microsoft Excel and other spreadsheet applications.

Can I use Excel Master Pro on mobile devices and tablets?

Absolutely! Excel Master Pro features a fully responsive design that works perfectly on smartphones, tablets, and desktop computers. The interface automatically adapts to different screen sizes with touch-friendly controls, optimized layouts, and mobile-specific interactions. You can access and use all features regardless of your device.

What happens to my data if I close the browser or refresh the page?

Since all processing happens locally in your browser, your data will be lost if you close the tab or refresh the page without downloading your work. We recommend frequently downloading your updated files to prevent data loss. For longer sessions, the tool includes undo/redo functionality to recover from mistakes, but persistent saving requires manual export.

How does Excel Master Pro compare to Microsoft Excel?

While Excel Master Pro doesn't include every advanced feature of Microsoft Excel (such as pivot tables, advanced charts, or VBA macros), it provides all the essential functions needed for most spreadsheet tasks. The advantage is instant access without installation, cost, or compatibility issues. For basic to intermediate spreadsheet work, data analysis, and quick calculations, Excel Master Pro delivers comparable functionality with greater accessibility.

Can I use Excel Master Pro without an internet connection?

Excel Master Pro requires an initial internet connection to load the application in your browser. However, once loaded, many of the core functions will continue to work if you lose connectivity, as the processing happens locally. For full functionality and to ensure you have the latest version, we recommend using it with an active internet connection.

Are there any limitations on file size or number of rows/columns?

Excel Master Pro can handle reasonably large datasets, but performance may vary based on your device's capabilities and browser. For optimal performance, we recommend files with up to 10,000 rows and 50 columns. Extremely large files may experience slower processing. The tool is continuously optimized to handle larger datasets efficiently.
