Node.js Script for Basic Analytics Data Pre-processing

We're Quantara AI, a Canadian AI enterprise analytics company, and I need a simple Node.js script to help us pre-process incoming raw analytics data (CSV/JSON) into a more structured format for our internal systems.

Scope & Requirements:

I am looking for an entry-level Node.js developer to build a straightforward script. The main task is to read specific data points from either CSV or JSON input files, perform some basic cleaning and transformation (e.g., date parsing, type conversion), and then output the data into a standardized JSON structure. We'll provide clear sample input files and output specifications.

Key Deliverables:

• A functional, well-commented Node.js script that can process the specified input files and generate the desired output, along with brief instructions on how to run it.
