Change sanitization check for `ExportDataAsCode` (#3837) 

* Change sanitization check for `ExportDataAsCode`

I opted to use `isalnum` function since it should handle most cases. It
cannot however handle cases of files beginning with numbers.

* Update `ExportDataAsCode` condition

* Reinsert comment on `ExportDataAsCode`
