Tips for transforming an array of images (from an input field) into a JSON string

After creating an array of images using

var a = Array.from(document.getElementById("id").files);

I tried to generate a JSON string of that array using

var b = JSON.stringify(a); 

However, all I get is an empty array. It seems like this issue is common with stringify, and despite researching extensively, I haven't been able to find a solution.

Answer №1

If your array of images consists of valid File objects, they are considered as a type of binary data known as blob.

Although JSON.Stringify does not directly support blobs, there are some workarounds available. Check out this solution: JSON.stringify or how to serialize binary data as base64 encoded JSON?
