To open a file that was created in another file format, either in an earlier version of Excel or in another program, click File > Open. If you open an Excel 97-2003 workbook, it automatically opens in Compatibility Mode.

People also ask

Is an Excel file secure?
An Excel file is only as secure as where you store it. While you can add a password to open a workbook (Go to File > Info > Protect Workbook), this is not military-grade encryption. If you have highly sensitive customer data, avoid emailing Excel files back and forth. Instead, store them in a secure cloud environment where you can control who has access to the link.

What happens if I save a macro file (.xlsm) as a standard file (.xlsx)?
If you do this, Excel will give you a warning. If you proceed, the file will be saved, but all your macros (the VBA code) will be stripped out and deleted permanently. The data and formatting will remain, but the automation buttons will stop working. Always check the file type before saving if you have written custom scripts.
