# Read from Grid

The "Read from Grid" Step allows you to get data from an existing AirOps Grid directly into your workflow.

### How to Configure the Read from Grid Step

#### Select a Grid

Choose the specific Grid you want to import data from. The dropdown will show all available Grids in your workspace.

#### Filtering Options

You can optionally filter the rows you want to import from the selected Grid:

* **All Rows**: Import all rows from the selected Grid
* **Selected Rows**: Import only specific rows based on your criteria

#### Column Selection

Choose which columns from the Grid you want to import:

* **All Columns**: Import all columns from the selected Grid
* **Selected Columns**: Specify only certain columns to import

### Output Format

The Read from Grid step outputs data in a structured format that can be easily used in subsequent steps of your workflow. The output will be an array of objects, with each object representing a row from the Grid.

Each row includes a special `__id` field that contains the unique identifier for that row. This `__id` is essential if you need to update specific rows later using the "Add Rows in Grid" step.

Example output:

```json
[
  {
    "__id": "123",
    "column1": "value1",
    "column2": "value2",
    "column3": "value3"
  },
  {
    "__id": "456",
    "column1": "value4",
    "column2": "value5",
    "column3": "value6"
  }
]
```

> **Note**: The `__id` field is automatically included in the output and represents the internal row identifier. You'll need this value when updating existing rows in your Grid.
