Use a google spreadsheet as a json store

In your spreadsheet, go to File > Publish to the web and click on "Web Page" drop down and select "Comma-separated values" and then copy the link. Assuming the link is in the variable link.

const fetchStore = require('google-spreadsheet-as-json');

fetchStore(link, (err, data) => console.log(data));

For a csv containing:

partner,state,date
all,karnataka,05/02/2018
other,delhi,05/02/2018

The output will be:

{ 
  all: { 
    karnataka: [ '05/02/2018' ] 
  },
  other: { 
    delhi: [ '05/02/2018' ] 
  }
}
