How to import xlsx file in through java script ?

Dear friends,

I have transition where user can upload xlsx file, I need to read the xlsx file through javascript to perform some validation. could you please help me in this.
  • By "upload", do you mean attach a file? If so, then doing it in JavaScript will be difficult. The file will be stored either in the BLOBS table in the AE database or as a file on a server, depending on how SBM is configured. JavaScript is generally prevented from performing database or server file access operations directly.

    If file attachments are stored on the file system (not in the database) then you might be able to use AppScript alone or in combination with an ASP script to do the file validation.
