Issue with dealing sheet that are protected although we could read but not able to iterate the rows

[hariharansethu]

@monitorjbl I could able to open the excel in compatibility mode but through code I am facing the issue as such the cellTypeEnum returns numeric and throws error.

Thought to do a workaround by check if a sheet is protected or not but it looks like there is no option to check .

Any help on this would be appreciated.Thanks !!
