Make a File Truly Secure
Security is a sliding scale, and I’d hesitate to say anything is ever completely secure. You can make Excel workbooks fairly secure by adding password protection and encryption. Be sure to use a strong password (eight-plus characters, upper- and lowercase, include numbers and symbols).
You can also protect access to files through Windows by using the NT Encrypting File System and using the Windows file security settings to prevent access by users other than yourself.
Finally, you can set permissions on a workbook using IRM to prevent any user other than yourself from reading or writing to the workbook in Excel. This last technique also provides a way to share workbooks in a secure way with restricted permissions.
