How to generate CSV file through Automation Script

if you are using  javascript in the automation you can generate the CSV something like here. And then you need to convert the csv data to file and attach it to an email .

Or if you are using velocity script then try to create a widget api and expose some method that would convert your data to csv , and use that in your automation

Thanks Satish Kumar (3sides) ! We are using javascript in the automation. So as you suggested we are able to generate data, but unable to create CSV file using the below code

csvFile = new Blob([csv], {type: 'text/csv'});.

Getting the attached error community.telligent.com/.../1357277

Any other option to create the CSV file.
