QR Attendance — RMMC BACOMM

Import Enrollment List (Excel)

Upload the enrollment list exported from your system (.xlsx). Only Student No. and Name are read in — everything else is ignored. Students are automatically grouped by Year Level.

Google Sheets Connection

Every scan is sent live to a Google Sheet through a small Apps Script you deploy once. See setup steps below.

Apps Script Web App URL

Event Name

One-time Google Apps Script Setup

Do this once per Google Sheet you want attendance to sync to.

Open (or create) the Google Sheet you want attendance saved to.
Go to Extensions → Apps Script.
Delete any starter code and paste the script shown below.
Click Deploy → New deployment. Choose type Web app.
Set "Execute as" to Me, and "Who has access" to Anyone.
Click Deploy, authorize when prompted, then copy the Web app URL.
Paste that URL into the field above and click Save Settings, then Send Test Row — check your Sheet for a row that says TEST.

function doPost(e) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Attendance");
  if (!sheet) {
    sheet = ss.insertSheet("Attendance");
    sheet.appendRow(["Event", "Date", "Time", "Student ID", "Name", "Year Level", "Section", "Mode"]);
  }

  var data;
  try {
    if (e && e.postData && e.postData.contents) {
      data = JSON.parse(e.postData.contents);
    } else if (e && e.parameter && Object.keys(e.parameter).length) {
      data = e.parameter;
    } else {
      sheet.appendRow(["DEBUG", new Date().toString(), "", "", "No postData received. e = " + JSON.stringify(e)]);
      return ContentService.createTextOutput(JSON.stringify({ status: "no_data" }))
        .setMimeType(ContentService.MimeType.JSON);
    }
  } catch (err) {
    sheet.appendRow(["PARSE_ERROR", new Date().toString(), "", "", String(err)]);
    return ContentService.createTextOutput(JSON.stringify({ status: "error", message: String(err) }))
      .setMimeType(ContentService.MimeType.JSON);
  }

  sheet.appendRow([
    data.eventName || "",
    data.date || "",
    data.time || "",
    data.id || "",
    data.name || "",
    data.yearLevel || "",
    data.section || "",
    data.mode || ""
  ]);
  return ContentService.createTextOutput(JSON.stringify({ status: "ok" }))
    .setMimeType(ContentService.MimeType.JSON);
}

function doGet(e) {
  return ContentService.createTextOutput("QR Attendance endpoint is live.");
}

Because Google Apps Script doesn't send back normal browser CORS headers, this app posts data "blind" (it can't read the reply). Every scan is also kept in this app's local log as a backup, so nothing is lost even if a sync silently fails — use Retry Pending Sync on the Log tab if you were ever offline.

If a row still doesn't appear after sending a test: check the Sheet for a row starting with DEBUG or PARSE_ERROR — it will show you the exact reason the script gave up. Also open Deploy → Manage deployments in the Apps Script editor and confirm "Who has access" is set to Anyone, not "Anyone with Google account" — the app sends requests anonymously, so a login-restricted deployment will reject them without any visible error on your end.
