# Data nodes
> Control which products flow through your automation. Pick a product set, narrow it with filters, or read data from a file so each run targets exactly the right products.
Data nodes decide which products your automation works on. Use them to pick a product set, narrow it down with filters, or pull in data from a file.
Place data nodes between your trigger and your actions. This controls exactly which products reach each step.
## Pick which products to process
The Select Products node chooses which products the automation runs on. It is usually the first node after your trigger.
| Setting | What it does |
| --------------------- | --------------------------------------------------------------------------------------------------------- |
| **Filter conditions** | One or more conditions a product must match (for example, status is "Ready" or category is "Electronics") |
| **Condition logic** | Combine conditions with AND (all must match) or OR (any can match) |
| **Minimum matches** | Require a minimum number of matching products before the workflow continues |
Leave the filter conditions empty to select every product in your catalog.
## Narrow a set with filters
The Filter Products node trims a product set that is already moving through the workflow. Use it after a Select Products node or an import to cut the set down further.
| Setting | What it does |
| --------------------- | -------------------------------------------------------------- |
| **Filter conditions** | One or more conditions a product must match to stay in the set |
| **Condition logic** | Combine conditions with AND or OR |
Common ways to use it:
* Keep only imported products that are missing a description
* Narrow a set to one brand or price range
* Drop products that are already published
**Select Products vs. Filter Products:** Select Products builds a new set from your whole catalog. Filter Products narrows a set that is already flowing through the workflow.
## Pull in data from a file
The Read File node loads product data from a file stored in WISEPIM. Use it when your workflow needs to process a CSV, Excel, or JSON file.
| Setting | What it does |
| ------------------ | ---------------------------------------------------- |
| **File path** | Where the file lives in WISEPIM |
| **Format** | CSV, Excel, or JSON |
| **Column mapping** | Match each file column to a product field in WISEPIM |
