## Frequently asked questions

### How are nested JSON objects handled during CSV conversion?

Nested object keys are flattened into dot-delimited column headers (e.g., "customer.name", "customer.email") to preserve data hierarchy inside tabular sheets.

### Can I export the result directly as an Excel-compatible file?

Yes. The output includes an optional UTF-8 Byte Order Mark (BOM) to ensure special characters and accented text open perfectly in Microsoft Excel.

### What happens if some JSON objects have different keys?

The converter aggregates all unique keys across all array objects into a unified schema, filling missing keys in specific rows with empty values.
