FAQ
How are nested JSON objects handled in CSV conversion?
Nested objects are flattened using dot notation. For example, {"user": {"name": "John"}} becomes a column "user.name" with value "John". Arrays of primitives are joined with commas, while arrays of objects are stringified to preserve the complete data structure.
Why convert JSON to CSV?
Converting JSON to CSV is useful when you need to integrate data into a system that only accepts CSV format. JavaScript Object Notation - Lightweight data interchange format can be transformed into CSV (Comma-Separated Values - Simple tabular format) for better compatibility.
Is my data secure during conversion?

What is the maximum JSON file size supported?
Since processing happens in your browser, the limit depends on available memory. Generally, files up to 10 MB are processed without issues. For larger files, we recommend splitting them.
