⚡ Usage

Open your browser at public/index.php.

Select your Excel file, enter the table name in the database, and define a unique key if needed.

Click Upload & Import.

Logs will appear in real time with color indicators:

Blue → new insert  
Yellow → already exists  
Red → error  

🔧 Column Mapping

Automatic: The first row in the Excel file is used as headers; database columns will match these names.

Manual: You can customize column mapping if needed:

$importer->setMapping([
    "Excel Name"  => "db_name",
    "Excel Email" => "db_email"
]);

The table will be created automatically based on the mapping.

// Inisyalize importer
$importer = new ExcelToMySQL("chemin/fiche.xlsx", $pdo);

// Opsyonèl: mete non tab la ak kle inik
$importer->setTableName('users');
$importer->setUniqueKey('email');

// Kreye tab si li pa egziste
$importer->createTableIfNotExists();

// Insert / Update done

✅ Key Point pou Itilizatè

You do not need to create process.php. All backend processing is already included in the package.

You only need to run the project and open index.php in your browser to launch the web interface, upload your Excel file, and track logs (insert / exists / error) in real time.

All required folders (uploads/) are automatically created if they do not exist.

Pake a sipòte:

1. Automatic Database Creation

If the database does not exist → it is created automatically with a log:
Database 'xxx' did not exist, it was created automatically ✅

If it already exists → it is not recreated:
Database 'xxx' already exists ⚠️

If a connection error occurs → log message:
Database connection error 'xxx': [error details] ❌

2. Automatic Table Creation

Tables are created based on Excel headers.

Empty headers are ignored.

Completely empty rows are removed.

3. Insert / Update

Inserts new rows if they do not exist.

Updates rows if the unique key already exists.

Logs display each action.

4. Dynamic Logs

Filter logs by type (insert, update, exists, error, info).

Log container adjusts height dynamically.

Auto-scroll to the latest log.

5. Progress Bar

Displays import progress based on the number of rows processed.
