Features Guide

Flattening

Normally, nested JSON like {"user": {"id": 1}} breaks CSVs. Enabling Flatten Nested JSON turns this into a column named user.id automatically.

Delimiter Control

European Excel versions often use semicolons (;) instead of commas. Use the delimiter dropdown to customize your output format for compatibility.
