# Evaluation Trigger node

Use the Evaluation Trigger node when setting up [evaluations](/08-0-0-Workflow/advanced-ai/evaluations/overview.md) to validate your AI workflow reliability. During evaluation, the Evaluation Trigger node reads your evaluation dataset from Google Sheets, sending the items through the workflow one at a time, in sequence.

On this page, you'll find the Evaluation Trigger node parameters and options.

```{note} Credentials for Google Sheets
The Evaluation Trigger node uses data tables or Google Sheets to store the test dataset. To use Google Sheets as a dataset source, configure a [Google Sheets credential](/08-0-0-Workflow/integrations/builtin/credentials/google/index.md).
```

## Parameters

- **Source:** Select the location to which you want to output the evaluation results. Default value is **Data table**.

    Source settings differ depending on **Source** selection.

    * When **Source** is **Data table**:
        * **Data table:** Select a data table by name or ID.
        * **Limit Rows**: Whether to limit the number of rows in the data table to process. Default state is `off`.
            * **Max Rows to Process**: When **Limit Rows** is enabled, the maximum number of rows to read and process during the evaluation. Default value is 10.
            * **Filter Rows:** Whether to filter rows in the data table to process. Default state is `off`.
     * When **Source** is **Google Sheets**:
        - **Credential to connect with**: Create or select an existing [Google Sheets credentials](/08-0-0-Workflow/integrations/builtin/credentials/google/index.md).
        * **Document Containing Dataset**: Choose the spreadsheet document with the sheet containing your test dataset.
            - Select **From list** to choose the spreadsheet title from the dropdown list, **By URL** to enter the url of the spreadsheet, or **By ID** to enter the `spreadsheetId`. 
            - You can find the `spreadsheetId` in a Google Sheets URL: `https://docs.google.com/spreadsheets/d/spreadsheetId/edit#gid=0`.
        * **Sheet Containing Dataset**: Choose the sheet containing your test dataset.
            - Select **From list** to choose the sheet title from the dropdown list, **By URL** to enter the url of the sheet, **By ID** to enter the `sheetId`, or **By Name** to enter the sheet title. 
            - You can find the `sheetId` in a Google Sheets URL: `https://docs.google.com/spreadsheets/d/aBC-123_xYz/edit#gid=sheetId`. 
        * **Limit Rows**: Whether to limit the number of rows in the sheet to process.
            * **Max Rows to Process**: When **Limit Rows** is enabled, the maximum number of rows to read and process during the evaluation.
        * **Filters:** Filter the evaluation dataset based on column values.
            * **Column**: Choose a sheet column you want to filter by. Select **From list** to choose the column name from the dropdown list, or **By ID** to specify an ID using an [expression](/08-0-0-Workflow/code/expressions.md).
