Helper IInput string was not in a correct format - Unexpected error on parallels desktop on Mac
I solved this it looks like by the help of this link https://support.microsoft.com/en-in/help/942460/system-formatexception-occurs-when-attempting-to-convert-a-numeric-str
I changed my region settings (under additional date, time and region settings) to English* (Australian) and Australia and then changed back to English (United States) and United States. For the first time I was able to save and import Excel data without the issue.
I will test it somewhat more, before I close the case as solved.
