JSON Format Requirements

Your JSON must be an array of objects. Each object becomes a row in the CSV, and the keys become column headers. All objects should have similar keys for consistent columns. If objects have different keys, all unique keys will be included as columns, with missing values left empty.

CSV Output Format

The converter produces standard CSV format with comma separators and UTF-8 encoding. Values containing commas, newlines, or double quotes are automatically wrapped in double quotes, with internal quotes escaped by doubling them. This ensures compatibility with Microsoft Excel, Google Sheets, and other CSV parsers.
