Hi,
I have 2 questions on download of dataset as part of dataiku app:
1. Is it possible to download the dataset in JSON format? I don't see the option in dropdown file type options.
2. If we download as csv, is it possible to customize the downloaded file name like add the download date, or change downloaded file name automatically?
Thanks,
Aastha

Hi Aastha,
Exporting as JSON is not supported.
You can copy a row from explore as json. This is useful for testing API queries to Prediction API endpoints.
You can use a Python recipe and write the JSON to a managed folded and then download the managed by browsing that folder.import dataiku import pandas as pd import numpy as np from dataiku import pandasutils as pdu from datetime import datetime # Read recipe inputs ticket_search_csv = dataiku.Dataset("dataset_name") ticket_search_csv_df = ticket_search_csv.get_dataframe() output_folder = dataiku.Folder("B9rFvU0O") output_folder_info = csm_json.get_info() # Get the current date and time current_date_time = datetime.now() # Format the date as YYYY-MM-DD-HH date_formatted = current_date_time.strftime("%Y-%m-%d-%H") # Create the filename with the formatted date filename = f"filename_prefix_{date_formatted}.json" #for local folders for remote folders S3 see get_writer/ upload_stream https://knowledge.dataiku.com/latest/code/managed-folders/tutorial-managed-folders.html path = output_folder.get_path() # Save the DataFrame to a JSON file with the updated filename ticket_search_csv_df.to_json(path + "/" + filename, orient="records"
