# ION Importers

The ION Importers provide bulk CSV import for manufacturing data. They give a spreadsheet-like interface where users upload files to create or update records:

* Real-time validation — validates data as users type (parts exist, locations valid, etc.)
* Bulk operations — import up to hundreds of records at once
* Multiple entity types — Parts, Inventory, Suppliers, Locations, Tools, BOMs, Purchase Orders, etc.
* Update or create — Inventory importer can update existing records or create new ones
* Custom attributes — supports custom fields per entity type
