HTML Input="file" Accept Attribute File Type (CSV)

Question

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?

Answer 1

Well this is embarrassing... I found the solution I was looking for and it couldn't be simpler. I used the following code to get the desired result.

<input id="fileSelect" type="file" accept=".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" />   

Valid Accept Types:

For CSV files (.csv), use:

<input type="file" accept=".csv" /> 

For Excel Files 97-2003 (.xls), use:

<input type="file" accept="application/vnd.ms-excel" /> 

For Excel Files 2007+ (.xlsx), use:

<input type="file" accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /> 

For Text Files (.txt) use:

<input type="file" accept="text/plain" /> 

For Image Files (.png/.jpg/etc), use:

<input type="file" accept="image/*" /> 

For HTML Files (.htm,.html), use:

<input type="file" accept="text/html" /> 

For Video Files (.avi, .mpg, .mpeg, .mp4), use:

<input type="file" accept="video/*" /> 

For Audio Files (.mp3, .wav, etc), use:

<input type="file" accept="audio/*" /> 

For PDF Files, use:

<input type="file" accept=".pdf" />

NOTE:

If you are trying to display Excel CSV files (.csv), do NOT use:

• text/csv
• application/csv
• text/comma-separated-values (works in Opera only).

If you are trying to display a particular file type (for example, a WAV or PDF), then this will almost always work...

 <input type="file" accept=".FILETYPE" /> 

Answer 2

These days you can just use the file extension

<input type="file" ID="fileSelect" accept=".xlsx, .xls, .csv"/>
