I have a file upload object on my page:

<input type="file" ID="fileSelect" />

with the following excel files on my desktop:

  1. file1.xlsx
  2. file1.xls
  3. file.csv

I want the file upload to ONLY show .xlsx, .xls, & .csv files.

Using the accept attribute, I found these content-types took care of .xlsx & .xls extensions...

accept= application/vnd.openxmlformats-officedocument.spreadsheetml.sheet (.XLSX)

accept= application/vnd.ms-excel (.XLS)

However, I cannot find the correct content-type for an Excel CSV file! Any suggestions?

EXAMPLE: http://jsfiddle.net/LzLcZ/

html csv file-upload input content-type
