Examples

1. Batch Processing Large Sales Logs

Data Analyst
Background
An analyst has a 50,000-row sales log that exceeds the import limit of their reporting software.
Problem
The file is too large to import in one go, causing system timeouts.
How to Use

Example Config
rowsPerFile: 5000, includeHeader: true, outputFormat: 'csv'
Outcome
The tool generates 10 smaller CSV files, each with the original header, allowing for successful batch imports.

2. Converting Data for Web Integration

Web Developer
Background
A developer needs to display a large product list on a website but needs the data in JSON format.
Problem
The source data is in CSV format and is too large to convert manually.
How to Use

Example Config
outputFormat: 'json'
Outcome
