A FEW PRACTICAL ANSWERS
Before you open
that workbook.
Your file stays local. Your original stays intact. Your next step stays simple.
Is this online Excel editor free?
Yes. You can open, edit, and download spreadsheets without an account or a subscription.
Does my spreadsheet leave my device?
No. The spreadsheet engine runs in your browser. File contents are processed locally and are not uploaded to ExcelCraft.
Does ExcelCraft replace Microsoft Excel?
It is useful for quick spreadsheet work. The underlying engine is in alpha, so complex workbooks may render or behave differently. Check important results in your usual spreadsheet application.
Will my work be saved automatically?
No. Download your workbook before closing or refreshing the editor. There is no cloud storage or recovery service.
Can I use VBA macros?
No. VBA macros are not executed. Do not rely on this editor to preserve macro workflows or unsupported workbook features.
