The **readJSON** method can read JSON files from a local disk, over the internet, or directly from input file objects.
### **Reading JSON files from local disk**
{% tabs %}
{% tab title="Node.js" %}
```javascript
const dfd = require("danfojs-node")
dfd.readJSON("./user_names.json")
.then(df => {
df.head().print()
}).catch(err=>{
console.log(err);
})
```
{% endtab %}
{% endtabs %}
### **Reading JSON files from a URL**
By specifying a valid URL, you can load JSON files from any location:
{% tabs %}
{% tab title="Node.js" %}
```javascript
const dfd = require("danfojs-node")
dfd.readJSON("https://raw.githubusercontentdatasets/master/finance-charts-apple.json")
.then(df => {
df.head().print()
}).catch(err=>{
console.log(err);
})
```
{% endtab %}
{% tab title="Browser" %}
```markup
Document
```
{% endtab %}
{% endtabs %}
### **Reading an input file object in the browser**
By specifying a valid [file object](https://developer.mozilla.org/en-US/docs/Web/API/File), you can load a JSON file in the browser:
{% tabs %}
{% tab title="Browser" %}
```markup
Document
```
{% endtab %}
{% endtabs %}
