Allow members to upload CSV files to collection?

Hi there, I’m working on a dynamic page where users can upload and visualize CSV data in my particular format. I cannot seem to use the FileReader() javascript call or the stock Upload buttons to let users select CSV or even TXT files, even though they are said to be supported by the Media Manager and I can upload them manually in the Content Manager. I want users to be able to either upload the whole CSV file to a collection or parse it into JSON string and upload that. I know I can do the latter by having users copy and paste into a text box then parsing that data, but I would rather just save/load the files themselves.

Upload Button file types and sizes supported in Wix:

File Types
Image : jpeg, png, jpg
Document : pdf, doc, docx, ppt, pptx, xls, xlsx, odp, odt, epub
Video: .avi, .mpeg, .mpg, .mpe, .mp4, .mkv, .webm, .mov, .ogv, .vob, .m4v, .3gp, .divx, .xvid.
Note: You cannot upload password protected documents.

File Size Limits
Image: 25MB
Document: 25MB
Video: 15MB

You can currently only use CSV files to import and export your own things into Wix like Contacts, Datasets etc.
