I am giving a spreedsheet and I need to convert into JSON. 
I have the following spreadsheet as so:

[![enter image description here](https://i.stack.imgur.com/XUrwf.png)](https://i.stack.imgur.com/XUrwf.png)

In essence, I'd need to convert into like this: 

```
{ "CompanyA": {
    "Products": ["Beds", "Knifes", "Spoons"]
}, "CompanyB": {
    "Products": ["Beds", "Knifes", "Spoons"],
    "Sites": ["West Coast", "East Coast"]
}, "CompanyC": {
    "Office": ["Los Angeles"]
}}

```

I tried looking at online sources, but I haven't got a good solution to what I am looking for
