Technical Details

Flattening Logic

Simple JSON arrays convert 1:1. However, nested objects are often "flattened" using dot notation (e.g., `user.address.city`). Our converter aims to keep headers clean by focusing on the standard key-value pairs of the top-level objects.

Handling Differences

Not all JSON objects in an array may have the same keys. The converter scans the data to create a superset of all unique keys to ensure no data is lost during the table creation.

Delimiter Standards

While CSV stands for *Comma* Separated, some regions use semicolons due to decimal comma usage. Our tool defaults to the standard RFC 4180 comma delimiter for maximum compatibility.
