At the bottom of the page: 1. Upload a file with two columns: `BARCODE` and `PLATE_INDEX`. This file must contain a header for each column. 2. Choose a separator (e.g., Tab). 3. Click the `Load File` button. 4. The plates will be automatically renamed using the barcodes included in the file. The preferred column names are `BARCODE` and `PLATE_INDEX`. If your file uses different column names, you will need to map the column names to the expected ones. ![Upload a barcode file for plate mapping](https://cdn.document360.io/dde9293e-c107-4b3e-9774-9c9c296ed970/Images/Setting/assay-exec-plate-mapping-barcode-info.png?sv=2026-02-06&spr=https&st=2026-11-10T21%3A36%3A21Z&se=2026-11-10T22%3A36%3A21Z&sr=c&sp=r&sig=73SsCE%2BFlDfHcQrSTelCZlA%2F5OVnM3bYE7WQbQPcTZk%3D)
