Quick answers to common questions:

• • File won't open? Make sure it's in XLSX or XLS format and under 10 MB. Try opening it in Excel first to verify it's not corrupted.
• • Formula not working? Check for typos in cell references. Most standard Excel functions work, but some advanced features aren't supported yet.
• • Lost your work? The editor doesn't auto-save. Download your file regularly to avoid losing changes.
• • Privacy concerns? All files are processed locally in your browser. We never see or store your data.
