JSON Arrays
Input must be a JSON array of objects. Each object becomes a row; keys become column headers.
📋
CSV Format
Comma-Separated Values — each line is a row, values separated by your chosen delimiter.
🔍
Type Inference
CSV→JSON: numbers and booleans are auto-detected so "42" becomes 42, "true" becomes true.
🗂️
Nested Objects
Nested object keys are flattened using dot notation: {"a":{"b":1}} → "a.b" column.
