+# 📥 Import Automatique d'Utilisateurs depuis Excel
+
+Ce script permet d'importer automatiquement des utilisateurs dans MongoDB depuis un fichier Excel.
+
+## 🚀 Utilisation
+
+### 1. Préparer le fichier Excel
+
+Placer votre fichier `.xlsx` dans le dossier `public/list_users/`
+
+**Format attendu :**
+```
+Nom Etudiant | Prénom Etudiant | Matricule HE | EMail Etudiant 2
+```
+
+**Exemple :**
+```
+Albarran Perez | Tamara | 1240935 | tamara.albarran@student.ihecs.be
+Amjahed | Kawtar | 1241004 | kawtar.amjahed@student.ihecs.be
+```
+
+**Nom du fichier :** Le nom doit être le nom du référent avec underscores.
+- ✅ `Emmanuel_WATHELE.xlsx`
+- ✅ `Sophie_MARTIN.xlsx`
+- ❌ `liste.xlsx`
+
+### 2. Configurer le script
+
+Ouvrir `scripts/import-users.js` et modifier ces lignes :
+
+```javascript
+const XLSX_FILENAME = "Emmanuel_WATHELE.xlsx"; // ⚠️ Nom du fichier
+const DEFAULT_PASSWORD = "IHECS-2025";         // Mot de passe par défaut
+const COURS = "Ouverture à l'esprit critique"; // Nom du cours
+```
+
+### 3. Lancer l'import
+
+```bash
+node scripts/import-users.js
+```
+
+## 📊 Ce que fait le script
+
+1. ✅ Lit le fichier Excel
+2. ✅ Extrait le référent depuis le nom du fichier (`Emmanuel_WATHELE` → `Emmanuel WATHELE`)
+3. ✅ Hash le mot de passe une seule fois (optimisation)
+4. ✅ Pour chaque étudiant :
+   - Vérifie que l'email est valide
+   - Vérifie que l'email n'existe pas déjà
+   - Crée l'utilisateur avec :
+     - `nom`, `prenom`, `email`
+     - `referent` (extrait du nom du fichier)
+     - `cours` (défini dans le script)
+     - `password` hashé
+     - `role: "USER"`
+   - Crée une balance initiale (3 000 000 tokens)
+5. ✅ Affiche un résumé détaillé
+
+## 📝 Exemple de résultat
+
+```
+🚀 Démarrage de l'import...
+
+📋 Référent: Emmanuel WATHELE
+📚 Cours: Ouverture à l'esprit critique
+🔑 Password par défaut: IHECS-2025
+
+📁 Lecture du fichier: C:\...\public\list_users\Emmanuel_WATHELE.xlsx
+✅ 50 lignes détectées dans le fichier
+
+🔐 Hash du mot de passe...
+🔌 Connexion à MongoDB...
+✅ Connecté à MongoDB
+
+📥 Import en cours...
+
+[1/50] ✅ Créé: Tamara Albarran Perez (tamara.albarran@student.ihecs.be)
+[2/50] ✅ Créé: Kawtar Amjahed (kawtar.amjahed@student.ihecs.be)
+[3/50] ⏭️  Ignoré (existe déjà): nezaket.arslan@student.ihecs.be
+...
+
+============================================================
+📊 RÉSUMÉ DE L'IMPORT
+============================================================
+✅ Utilisateurs créés: 48
+⏭️  Utilisateurs ignorés (déjà existants): 2
+❌ Erreurs: 0
+============================================================
+
+✨ Import terminé !
+```
+
+## ⚠️ Important
+
+- Le script **ignore** les utilisateurs déjà existants (même email)
+- Le script **ignore** la colonne "Matricule HE" (non sauvegardée)
+- Tous les utilisateurs auront le **même mot de passe** (ils pourront le changer après)
+- Chaque utilisateur reçoit **3 000 000 tokens** par défaut
+
+## 🔧 Dépannage
+
+**Erreur : "Cannot find module 'xlsx'"**
+```bash
+npm install xlsx
+```
+
+**Erreur : "connect ECONNREFUSED"**
+- Vérifier que MongoDB est démarré
+- Vérifier la connexion dans `.env.local`
+
+**Erreur : "File not found"**
+- Vérifier que le fichier est bien dans `public/list_users/`
+- Vérifier le nom du fichier dans le script
