Sample Json

```
data:[{"varExchange":"ftx","varPrice":482.3},{"varExchange":"ftx","varPrice":481.8}]

```

1. I want to change the name of the key from "varExchange" to "name" and "varPrice" to "qty"
2. I need to remove the double quotes for key.

Output Like

```
 data:[{name:"test","qty":482.3},{name:"test","qty":481.8}]

```

Kindly help me to fix this.
Thanks
