+# Custom formatting values
+
+By default Laravel Excel uses PHPExcel's default value binder to intelligently format a cells value when reading it. You may override this behavior by passing in your own value binder to suit your specific needs. Value binders must implement PHPExcel_Cell_IValueBinder and have a bindValue method. They may also extend PHPExcel_Cell_DefaultValueBinder to return the default behavior.
+    
+    use PHPExcel_Cell;
+    use PHPExcel_Cell_DataType;
+    use PHPExcel_Cell_IValueBinder;
+    use PHPExcel_Cell_DefaultValueBinder;
+
+    class MyValueBinder extends PHPExcel_Cell_DefaultValueBinder implements PHPExcel_Cell_IValueBinder
+    {
+        public function bindValue(PHPExcel_Cell $cell, $value = null)
+        {
+            if (is_numeric($value))
+            {
+                $cell->setValueExplicit($value, PHPExcel_Cell_DataType::TYPE_NUMERIC);
+
+                return true;
+            }
+            
+            // else return default behavior
+            return parent::bindValue($cell, $value);
+        }
+    }
+
+    $myValueBinder = new MyValueBinder;
+
+    Excel::setValueBinder($myValueBinder)->load('file.xls', function($reader) {
+
+        // reader methods
+
+    });
+
+Available PHPExcel_Cell_DataType's are TYPE_STRING, TYPE_FORMULA, TYPE_NUMERIC, TYPE_BOOL, TYPE_NULL, TYPE_INLINE and TYPE_ERROR
+
+To reset the value binder back to default and/or before calling Laravel Excel after setting a custom value binder you need to call the resetValueBinder method.
+
+    Excel::resetValueBinder();
