GET THE CELL VALUE FROM GIVEN DATASET¶
Extracts a single cell value from a tabular dataset given a row and column index. The column may be addressed by zero-based integer position or by column name. Use this worker whenever you need to pull one scalar value out of a dataset for downstream processing.
When to use¶
Classification: process.
Tagged: cell_value, dataset, index, keyvalue, lookup, scalar_extraction.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset Name | datasetname | dataset | — | The input tabular dataset from which the cell value will be extracted; must be a structured dataset object available in the workflow context. | |
| Row Index | row_index | scalar | 0 | Zero-based integer row index of the target cell (default: 0, i.e. the first row); leave at default to read from the first row. | |
| Col Index | col_index | scalar | 0 | Zero-based integer column index or column name string of the target cell (default: 0, i.e. the first column); pass a column header string to address by name instead of position. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_get_cell_value_output_1 | dataset_get_cell_value_output_1 | keyvalue | Key-value pair containing the extracted cell value; the value is null if the addressed row/column combination does not exist in the dataset. |
