When using CommaIO option to export the contents to a file, user would notice an additional quotation marks on each field.This is not seen when the file is opened as Excel, but in NotePad++.
Though this is not going to have major impact, there are situations when the file is consumed by other application to process further. In such cases, this would create problem.
So what is the solution ? I tried using TextIO in my code and it solved the problem 🙂
