Token Comma expected - can not run JSON query

Question

This is a problem i have working in Excels Power Query. I have this query saved in a variable named "content" which is passed to the call Web.Contents.

I can not run the query, i get "Token Comma expected" error. Can somebody tell what that is about?

`let
content = "{
"query": [
    {
      "code": "Region",
      "selection": {
        "filter": "vs:RegionKommun07",
        "values": [
          "1283"
        ]
      }
    },
    {
      "code": "Sysselsattning",
      "selection": {
        "filter": "item",
        "values": [
          "FÖRV"
        ]
      }
    },
    {
      "code": "Alder",
      "selection": {
        "filter": "item",
        "values": [

If you want " inside a quoted string then you need to double them up like "" to escape them.

let
content = "{
""query"": [
    {
      ""code"": ""Region"",
      ""selection"": {
        ""filter"": ""vs:RegionKommun07"",
        ""values"": [
          ""1283""
        ]
      }
    },
    ...
    ...
    }"

To include quotes in a text value, the quote mark is repeated, as follows: "The ""quoted"" text" // The "quoted" text
