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

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

Are you struggling with allowing only certain file types to be uploaded using the HTML input element with the file type attribute? Specifically, are you having trouble finding the correct content-type for an Excel CSV file? 📁🗂️

Well, you've come to the right place! In this blog post, we'll address this common issue and provide you with easy solutions to ensure that your file upload functionality only allows .xlsx, .xls, and .csv files. Let's get started! 🚀

The Problem: Accepting Specific File Types

Let's begin by diving into the problem at hand. You have an HTML file upload object on your page, like this:

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

You want to restrict the file types that users can upload to only include .xlsx, .xls, and .csv files. To achieve this, you plan to use the accept attribute.

Finding the Correct Content-Type for CSV Files

You mentioned that you were able to find the correct content-types for .xlsx and .xls files, which are:

accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

and

accept="application/vnd.ms-excel"

respectively. But when it comes to CSV files, you're not sure which content-type to use. Don't worry, we've got your back! 😎

The correct content-type for Excel CSV files is:

accept="text/csv"

By specifying accept="text/csv", you can ensure that only CSV files are allowed to be uploaded.

Putting It All Together

Now that we've discovered the correct content-type for Excel CSV files, let's modify your HTML code to include the accept attribute for all the desired file types:

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

With the updated code, your file upload input element will only allow .xlsx, .xls, and .csv files to be selected by the user. 📄📊
