A FEW PRACTICAL ANSWERS
Before you open
that workbook.
Your file stays local. Your original stays intact. Your next step stays simple.
How do I open an XLS file online?
Choose an XLS file using the button above. Its worksheet values, formulas, and number formats are imported locally.
Why is my file not opening?
The file may be corrupt, too large, encrypted, or use an unsupported feature. The launch limit is 20 MB. Try a smaller, unencrypted copy.
Can I open files from Google Drive?
Download a local workbook first, then open it here. ExcelCraft does not connect to cloud drives.
Is an internet connection needed?
It is needed to load the editor. Workbook processing then takes place on your device. Offline reopening is not currently guaranteed.
