# Insert Bulk Seller Extensions

`POST /loaddata/SX`

Inserts multiple product extensions to the Master Data table.<p>
The `name` (a name of the category) and `sku` must be provided for each record in the header and data object within the request body.
The **/loaddata** operation is a very efficient and quick way to insert bulk data to the Master Data table.
The main advantage is its greater speed when loading thousands of records (compared to e.g. **/integrate**).<p>
Use the [ISO 8601](https://www.iso.org/iso-8601-date-and-time-format.html) date format (YYYY-MM-DD) if a date is included in the table.

<!-- theme: warning -->
>**Please note**:
> If no `joinFields` are provided in the request, then this operation will insert entire records. It means that in this case (without `joinFields`) with **/loaddata** it is not possible to update just some fields (for this use the **/integrate** endpoint instead). The source data must always contain the entire row’s content.
