Convert Google Spreadsheets to JSON using Javascript

Uses the google-spreadsheet library to fetch data.

The final JSON is based on sheets names and column titles and finally looks like this :

{
  "Customers": [
    {
      "name": "Sony",
      "country": "Japan"
    },
    {
      "name": "Renault",
      "country": "France"
    }
  ],
  "Invoices": [
    {
      "id": "F0001",
      "totalAmount": "12367.12"
    },
    {
      "id": "F0002",
      "totalAmount": "4398.2"
    }
  ]
}

This can be useful when you want people edit spreadsheets and need to work with the data.

QuickStart

extractSheets can use node callback pattern or async/await.

const { extractSheets } = require("spreadsheet-to-json");

// optional custom format cell function
const formatCell = (sheetTitle, columnTitle, value) => value.toUpperCase();

extractSheets(
  {
    // your google spreadhsheet key
    spreadsheetKey: "abch54Ah75feBqKGiUjITgE9876Ypb0yE-abc",
    // your google oauth2 credentials or API_KEY
    credentials: require("./google-generated-creds.json"),
    // optional: names of the sheets you want to extract
    sheetsToExtract: ["Customers", "Invoices"],
    // optional: custom function to parse the cells
    formatCell: formatCell
  },
  function(err, data) {
    console.log("Customers: ", data.Customers);
    console.log("Invoices: ", data.Invoices);
  }
);
