# Run a CSV through a lookup in bulk

Upload a CSV in the dashboard, choose a product and a column, and download the results when the job ends.

## Run a job

1. Open [jobs](https://lookvalid.com/dashboard/jobs) in the dashboard and upload your CSV.
2. Choose a live product and the column that holds the value to look up.
3. Start the job. It runs in the background; you can close the page.
4. Download the results when it shows completed.

## Cost

Each row runs through the same engine as an API call, so the same prices, billing rules and 7-day cache apply. On a success-billed product, a row that finds nothing, fails or is refused costs nothing; a per-call product charges every completed row. Before the job starts, the worst case is held on your balance, and whatever is not spent is released.

## Limits
