Examples

1. Converting Product Catalog

E-commerce Manager

Background: The manager has a product list in Excel with columns for ID, Name, and Price.
Problem: The website backend requires a JSON file to update the product catalog.
How to Use: Upload the product list, ensure 'First Row Contains Headers' is checked, and select 'Array of Objects'.
Example Config: hasHeader: true, trimValues: true, nestedFormat: 'object'
Outcome: A clean JSON file where each product is an object, ready for direct API ingestion.

2. Processing Raw Sensor Data

Data Analyst

Background: A sensor log is exported as an Excel file without headers, containing only raw numerical values.
Problem: The data needs to be converted into a simple array structure for a charting library.
How to Use: Upload the file, disable 'First Row Contains Headers', and select 'Array of Arrays'.
Example Config: hasHeader: false, nestedFormat: 'array'
Outcome: A nested JSON array containing only the raw data points, perfect for plotting graphs.
