Blocks structure with Big Data

OK. You could try something like this:

BLOCKS

SCRIPT

function doPost(e) {

var data = JSON.parse(e.postData.contents) ;
var ss = SpreadsheetApp.getActive(); //assumes script bound to spreadsheet
var sh = ss.getSheetByName('Sheet1');

for (var i=0;i<data.length;i++) {
sh.appendRow(data[i]);
}
return ContentService.createTextOutput("Success") ;
}
