# Excel / CSV

> Bring in anything you keep in a spreadsheet.

A spreadsheet is the most flexible source. Whatever your other systems lack, you can put in a file and import.

## Why use a spreadsheet

* **It works on every plan**, with nothing to connect.
* **It can hold anything.** Weights, compositions, country of origin, HS codes: if you can put it in a column, LUXIMA can read it.
* **It fills gaps.** Used alongside GS1, your ERP or your website, a spreadsheet supplies the fields those sources do not have.
* **You already have one.** Most product data starts life in a spreadsheet, or can be exported to one from another system.

## How to use it

**1. Get an example file**

On the **Integrations** page, click **Download example CSV** to see the layout LUXIMA expects.

**2. Start the import**

On the **Excel / CSV** card, click **Import a spreadsheet**. Add other sources if you want to merge them with your file.

**3. Upload and match columns**

Upload your file. LUXIMA recognises common column names, and you match the rest by hand.

The full steps, the columns LUXIMA understands and how rows become products are in [Import a spreadsheet](https://docs.luxima.io/import-export/import-a-spreadsheet.md).

## With other sources

A spreadsheet works well as the second source in a workflow.

| First source | What the spreadsheet adds |
| - | - |
| GS1 | Weight, composition, country of origin. |
| Website | GTINs, exact weights, HS codes. |
| NetSuite or Katana | Whatever your ERP does not record, such as composition. |

LUXIMA matches the rows to products by GTIN, then SKU, then product code. Make sure your file has at least one of those columns, with the same values your other source uses.
