How to dynamically import json data using Svelte

I have previously been testing a component using the following code

<script>import x from "/path/to/x.json"</script>

this, as expected loads the json file to variable x.

What I would like to do, is dynamically load a local json file given an <input> element e.g.

<script>let files ;function loadJSONFile(){  doSomething(files[0].name) ;}</script><input type="file" bind:files on:change={loadJSONFile}>

where doSomething() is doing the equivalent task of import in the first example.

Ideally, I could load the data from any local folder, so bind:files may not be appropriate, as files[0].name seems to yield a relative path, rather than an absolute path.
