How to create a method to edit fields (google sheets) for json call with google script

Question

This is the method created for reading, but I'm having trouble creating the function to edit and delete, if anyone can help I appreciate

function Read(e) {
  var rows = sheet.getRange(2, 1, sheet.getLastRow() - 1, sheet.getLastColumn()).getValues();
  var data = [];
  for (var i = 0; i < rows.length; i++) {
    var row = rows[i];
    var record = {};
    record['Data'] = row[0];
    record['House'] = row[1];
    record['Platform'] = row[2];
    record['Description'] = row[3];
    record['Type'] = row[4];
    record['WorkerSupplier'] = row[5];
    record['Image'] = row[6];
    record['Amount'] = row[7];
    record['Paid'] = row[8];
    data.push(record);
  } var result = JSON.stringify(data);
  return ContentService.createTextOutput(result).setMimeType(ContentService.MimeType.JSON);
}
