Hi,

I’m trying to make a custom widget that would generate a CSV File. It seems I’m reaching a dead end on getting the widget to work. Is there a proper process to do this?

I’m planning to store the generated CSV files into table records.

Hello,  
I have tried it but I have also got stuck. Error message is “base value did not pass the validation”. I would like to know if there are some acceptable formats for file type variables except url. Image file can accept some other formats like “data:image/png;base64,xxxx”. Thank you.

Hi @sasa

tldr.

1. Is storing Data in Base64 no option for you?
2. Is there a requirment to firstly show the data and then download these in csv file?
