Accessing a public google sheet's data directly from client-side JavaScript

Is there a way to get cell values of a public google spread sheet ?

GET https://sheets.googleapis.com/v4/spreadsheets/1vW01Y46DcpCC7aKLIUwV_W4RXLbeukVwF-G9AA7P7R0/values/A1A4?key=abcdef

returns 403.

I also sent the Referrer in Postman : Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.128 Safari/537.36

            }
        ]
    }
}

I am trying to access a public sheet's data directly from client-side JavaScript.

No round-trips to the server. I remember this was possible some 10 years ago but am unable to locate the docs.

Solution

  • You can access the public spreadsheet by json endpoint

    var id = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
var gid = '1111111111111';
var url = 'https://docs.google.com/spreadsheets/d/'+id+'/gviz/tq?tqx=out:json&tq&gid='+gid;

    Take a slice

    data.substring(47).slice(0, -2)

    and parse the json

    direct link

    https://docs.google.com/spreadsheets/d/1n-rjSYb63Z2jySS3-M0BQ78vu8DTPOjG-SZM4i8IxXI/gviz/tq?tqx=out:json&tq&gid=0

    example by gas

    function getEndpointJson(){
  var id = '1n-rjSYb63Z2jySS3-M0BQ78vu8DTPOjG-SZM4i8IxXI';
  var gid = '0';
  var txt = UrlFetchApp.fetch(`https://docs.google.com/spreadsheets/d/${id}/gviz/tq?tqx=out:json&tq&gid=${gid}`).getContentText();
  var jsonString = txt.match(/(?<="table":).*(?=}\);)/g)[0]
  var json = JSON.parse(jsonString)
  var table = []
  var row = []
  json.cols.forEach(colonne => row.push(colonne.label))
  table.push(row)
  json.rows.forEach(r => {
    var row = []
    r.c.forEach(cel => {
        try{var value = cel.f ? cel.f : cel.v}
        catch(e){var value = ''}
        row.push(value)
      }
    )
    table.push(row)
    }
  )
  return (table)
}

    example by html page

    For instance on html page (you have to store it in outside server)

    <html>
<title>Google Sheets json endpoint V4</title>
<author>Mike Steelson</author>
<style>
table {border-collapse: collapse;}
th,td{border: 1px solid black;}
</style>
<body>
<div id="json">json here</div>
<script>
var id = '1n-rjSYb63Z2jySS3-M0BQ78vu8DTPOjG-SZM4i8IxXI';
var gid = '0';
var url = 'https://docs.google.com/spreadsheets/d/'+id+'/gviz/tq?tqx=out:json&tq&gid='+gid;
fetch(url)
  .then(response => response.text())
  .then(data => document.getElementById("json").innerHTML=myItems(data.substring(47).slice(0, -2))  
  );
function myItems(jsonString){
  var json = JSON.parse(jsonString);
  var table = '<table><tr>'
  json.table.cols.forEach(colonne => table += '<th>' + colonne.label + '</th>')
  table += '</tr>'
  json.table.rows.forEach(ligne => {
    table += '<tr>'
    ligne.c.forEach(cellule => {
        try{var valeur = cellule.f ? cellule.f : cellule.v}
        catch(e){var valeur = ''}
        table += '<td>' + valeur + '</td>'
      }
    )
    table += '</tr>'
    }
  )
  table += '</table>'
  return table
}           
</script>
</body></html>

    The sheet ID you have provided is wrong.
