Parsing Excel Document

Please provide the following:

  1. SDK Version: 37
  2. Platforms(Android/iOS/web/all): All

I’ve tried several times over the last few months to parse an Excel document. Finally, I decided to put my head down and commit to figuring this out. However, it is not an easy task.

I’ve tried using DocumentPicker to get my document - this works.
I tried using FileSytem to convert the file to a base64 but FileSystem isn’t available on WEB currently so not an option.

I’ve tried using a couple different 3rd party libraries but it doesn’t appear that DocumentPicker returns the actual file in a manner that can be parsed.

The most recent attempt was to use SheetJS library (github.com/SheetJS).

Does anyone have any ideas on how to parse an Excel file that works on Android, iOS, and Web?
