Convert a csv file to a tab file

I have a csv file in my flow which I would like to export as a tab file. Is it possible using a python recipe? If so, what would that recipe be?

    Hi @raia

    You could export the dataset in your flow, and download it as a TSV (Tab Separated Values) formatted file, by clicking on the "Export" button, then specifying "\t" as the separator.

    Additionally, from a Python code recipe, you could output the CSV dataset to a managed folder as a TSV file using the Pandas Python library, as shown in the below example code:

    import dataiku
    import pandas as pd, numpy as np
    from dataiku import pandasutils as pdu
    # Read recipe inputs
    comma_separated_file = dataiku.Dataset("comma_separated_file")
    df = comma_separated_file.get_dataframe()
    # the name of the tab file
    file_name = 'tab_separated_file.tsv'
    # Write recipe outputs
    output_folder = dataiku.Folder("output_folder")
    with output_folder.get_writer(f"/{file_name}") as writer:
        writer.write(df.to_csv(sep='\t', encoding='utf-8', index=False).encode("utf-8"))
