One of the features of Google Forms is that responses can be collected on a spreadsheet automatically. However, Google Sheets API makes it possible to achieve this using regular HTML forms, as well. You can view the responses to this form here: https://docs.google.com/spreadsheets/d/1mkTuLONELStkaLTAtSSAAtpY1JghQ3Sdwb6PjVM8PZc/edit



Below is the code that runs on Google Scripts, if you are interested in making your own form-less form.

function getSheep(){
  return SpreadsheetApp.openById('1mkTuLONELStkaLTAtSSAAtpY1JghQ3Sdwb6PjVM8PZc').getSheetByName('Sheet1');
  //important: change if moving this file or if renaming the sheet
}

function doPost(e) {  
  var lock = LockService.getScriptLock();
  if (!lock.tryLock(10000)) {
    Logger.log('Lock not obtained: '+new Date().toUTCString());
    return HtmlService.createHtmlOutput("failure").setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
  }
  
  var sheep = getSheep();
  var row = sheep.getLastRow()+1;
  
  if(typeof e !== 'undefined'){
    sheep.getRange(row,  1).setValue(new Date().toLocaleString('en-US', { timeZone: 'Pacific' }));
    sheep.getRange(row,  2).setValue(e.parameter.data);
  }
  
  lock.releaseLock();
  return HtmlService.createHtmlOutput("success").setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
}
