Appending Datetime to JSON Output Filename in JSON Writer

I'm looking to add a datetime suffix to the filename of my JSON output using the JSON Writer, something like "file_name_2025-06-04 11_15_00.json". I came across a community post demonstrating how this can be done for a text file, but I haven’t been able to achieve the same for a JSON file.

Appreciate any suggestions or best practices the community can share.

Best Regards,

Dhaval.
