Writing 2D Data Arrays to a Google Spreadsheet from Google Apps Script Making an HTTP POST Request for CSV Data

Just a quick post to log another Google Apps script how to – this time how to grab a 2D array of CSV data from a URL and then paste it into a spreadsheet. For the trivial case, we could just as easily do this with an =importData() formula, but I’m still working out what bits of glue might be useful on the Apps script front…;-)

So – the demo function will take a blank spreadsheet and do this to it:

That is, shove some data from a query run over a data.gov.uk SPARQL endpoint into it.

Here’s the script – it shows how to HTTP POST a query from the Apps script to the SPARQLproxy endpoint, grab the results back as CSV, then convert them crom the CSV array to a range that can be posted into the spreadsheet.

function dgtest(){

  var s = SpreadsheetApp.getActiveSpreadsheet();
  var ss = s.getActiveSheet();
  var sc = ss.getActiveCell();

  //I really need to tweak this so we can enter a SPARQL query and then generate the args string from it...
  var args="query=prefix+sch-ont%3A+%3Chttp%3A%2F%2Feducation.data.gov.uk%2Fdef%2Fschool%2F%3E%0D%0ASELECT+%3Fschool+%3Fname+%3Fdate+%3Fdistrict+WHERE+{%0D%0A%3Fschool+a+sch-ont%3ASchool%3B%0D%0Asch-ont%3AestablishmentName+%3Fname%3B%0D%0Asch-ont%3AopenDate+%3Fdate%3B%0D%0Asch-ont%3AdistrictAdministrative+%3Fdistrict.%0D%0A}+ORDER+BY+DESC%28%3Fdate%29+LIMIT+15&output=csv&callback=&tqx=&service-uri=http%3A%2F%2Fservices.data.gov.uk%2Feducation%2Fsparql";

  var x=UrlFetchApp.fetch('http://data-gov.tw.rpi.edu/ws/sparqlproxy.php',{method: 'post', payload: args});
  var ret=x.getContentText();
  ret = CSVToArray( ret, "," );

  var arr = [];
  var c = [];
  for (var i=0;i < ret.length-1;i++) {
    for (var j=0; j< ret[0].length;j++){

  var destinationRange = ss.getRange(1, 1, i, j);

The CSV2Array function is one I found on Stack Overflow
