DATASET FORMAT COLUMN¶
Applies a printf-style format string to one or more columns in a dataset, returning the reformatted dataset. Use this worker to standardise string or numeric column representations (e.g. zero-padding, unit suffixes, decimal precision) before downstream processing.
When to use¶
Classification: process.
Tagged: column_formatting, dataset_transform, format_column, printf, string_format.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset | dataset_1 | dataset | — | Input dataset whose column(s) will be reformatted; accepts any tabular dataset available in the workflow context. | |
| Column Name | column_name | scalar | — | Name(s) of the column(s) to format; supply a single column name or a comma-delimited list (e.g. “speed,force”) when multiple columns share the same format string. | |
| Format String | format_string | scalar | %s | A printf-style format string (e.g. “%s”, “%.2f”, “%05d”) applied to each specified column; defaults to “%s” (no-op string passthrough); use a comma-delimited list to pair a distinct format with each column. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_format_column_output_1 | dataset_format_column_output_1 | dataset | A copy of the input dataset with the specified column(s) reformatted according to the supplied format string(s); all other columns are unchanged. |
