1. Buka Google Sheets Anda → klik menu Extensions → Apps Script
2. ⚠️ Jika Anda SUDAH PERNAH setup sebelumnya (ada fungsi readSetting, getRecord, setupMindsetApp, dll), JANGAN hapus semua kode! Cukup cari fungsi doPost(e) yang sudah ada, hapus fungsi itu saja, lalu tempel penggantinya di bawah ini (fungsi lain seperti doGet, readSetting, setupMindsetApp, jsonResponse dibiarkan seperti apa adanya):

function doPost(e) {
  try {
    const payload   = JSON.parse(e.postData.contents);
    const tes       = (payload.tes || '').toUpperCase();
    const sheetName = tes === 'NST' ? SHEET_NST : SHEET_TKD;

    const ss    = SpreadsheetApp.getActiveSpreadsheet();
    let   sheet = ss.getSheetByName(sheetName);
    if (!sheet) sheet = ss.insertSheet(sheetName);

    if (sheet.getLastRow() === 0 && payload.headers) {
      sheet.appendRow(payload.headers);
      const hr = sheet.getRange(1, 1, 1, payload.headers.length);
      hr.setFontWeight('bold');
      hr.setBackground('#D6E4F0');
      sheet.setFrozenRows(1);
      sheet.setColumnWidth(1, 160);
      sheet.setColumnWidth(3, 180);
    }

    // Ambil header ASLI dari baris 1 sheet (bukan asumsi urutan dari klien) —
    // ini membuat penulisan data KEBAL terhadap kolom yang disisipkan/diurutkan ulang manual.
    const lastCol      = Math.max(sheet.getLastColumn(), payload.headers ? payload.headers.length : 1);
    const sheetHeaders = sheet.getLastRow() > 0
      ? sheet.getRange(1, 1, 1, lastCol).getValues()[0]
      : (payload.headers || []);

    // Susun baris baru dengan MEMETAKAN tiap field berdasarkan NAMA header
    // (payload.headers[i] -> payload.values[i]), bukan berdasarkan posisi array.
    // existingRow (opsional) dipertahankan untuk kolom yang tidak dikirim klien.
    function petakanBarisByHeader(existingRow) {
      const row = existingRow ? existingRow.slice() : new Array(sheetHeaders.length).fill('');
      (payload.headers || []).forEach((h, i) => {
        let col = sheetHeaders.indexOf(h);
        if (col === -1) { sheetHeaders.push(h); col = sheetHeaders.length - 1; }
        while (row.length <= col) row.push('');
        row[col] = payload.values[i];
      });
      return row;
    }

    // MODE UPDATE (fitur Edit Data) — cari baris dg timestamp = row_key, lalu timpa
    if (payload.mode === 'update' && payload.row_key && payload.values) {
      const data  = sheet.getDataRange().getValues();
      const tsCol = sheetHeaders.indexOf('timestamp');
      let rowIndex = -1;
      if (tsCol > -1) {
        for (let i = 1; i < data.length; i++) {
          if (String(data[i][tsCol]) === String(payload.row_key)) { rowIndex = i + 1; break; }
        }
      }
      if (rowIndex > 0) {
        const newRow = petakanBarisByHeader(data[rowIndex - 1]);
        sheet.getRange(rowIndex, 1, 1, newRow.length).setValues([newRow]);
        return jsonResponse({ status: 'ok', sheet: sheetName, row: rowIndex, mode: 'updated' });
      }
      const newRow = petakanBarisByHeader(null);
      sheet.appendRow(newRow);
      return jsonResponse({ status: 'ok', sheet: sheetName, row: sheet.getLastRow(), mode: 'appended' });
    }

    if (payload.values) {
      const newRow = petakanBarisByHeader(null);
      sheet.appendRow(newRow);
    }
    return jsonResponse({ status: 'ok', sheet: sheetName, row: sheet.getLastRow() });

  } catch(err) {
    return jsonResponse({ status: 'error', message: err.message });
  }
}
