# Export a BOM to CSV

Download an asset's parts list as a CSV file, for example to share with a customer or edit in a spreadsheet before re-importing it.

### Steps

1. On the **BOM & Stock** tab, click **Export CSV**.
2. Signal downloads a file named `BOM_{serial number}_{timestamp}.csv`.

### What you see

The file contains one row per part, with these columns:

`partNumber, description, quantity, itemNumber, equipmentType, latestModel, newModelPartNumber, isSpare, parentPartNumber`

Nested parts keep their parent's part number in the `parentPartNumber` column, so you can see the tree structure when you reopen the file. These are the same columns used by the import template, so an exported file can be edited and re-imported.
