See a malformed file refused by the real importer, then cancel a valid preview without replacing the current bin.

## Reject a broken file and cancel a replacement

1. **Try the prepared invalid CSV**

   Try the prepared invalid CSV.

   The real parser refuses the broken file before replacing the dataset. Fix the source file and import it again.

2. **Load the prepared two-bin file**

   Load the prepared two-bin file.

   This visible training control supplies a prepared local CSV to the real importer. In the product, choose your own local file.

3. **Cancel the prepared file import**

   Cancel the prepared file import.

   Cancelling the preview keeps the current dataset. A file is not applied until its mapping has been reviewed.
