WRITE DATASET TO FILE

Serialises an in-memory dataset to a CSV file on disk. Writes the column headers followed by all rows in comma-separated format and returns the resulting file. Use this worker whenever a downstream step requires a dataset to be persisted as a flat file.

When to use

Classification: process.

Tagged: csv, dataset, export, file_output, write.

Inputs

Label ID Type Default Required Description
Response To Extract From responsetoextractfrom dataset   The dataset (tabular, in-memory) to be written to disk; each row becomes a CSV line with column headers derived from the dataset keys.
File Name file_name scalar Unknown   Desired output filename (including extension, e.g. ‘results.csv’); defaults to ‘Unknown’ if left blank — always provide a meaningful name so the file is identifiable downstream.

Outputs

Label ID Type Description
dataset_write_to_file_output_1 dataset_write_to_file_output_1 file The generated CSV file written to the platform’s temporary directory; contains a header row followed by all dataset rows in comma-separated format, ready for download or further processing.
