JSON to CSV Converter

JSON to CSV conversion transforms JavaScript Object Notation (JSON) data into a Comma-Separated Values (CSV) format that can be opened in spreadsheet applications like Excel, Google Sheets, or LibreOffice Calc.

This tool supports three conversion modes:

• Standard — Converts an array of objects into CSV rows. The keys of the first object become column headers.
• Flatten — Flattens nested objects using dot notation (e.g., address.city) so deeply nested JSON becomes flat CSV columns.
• Simple — Converts a single object into two columns (key, value), one row per property.

1. Paste your JSON — Copy and paste any JSON data into the input textarea. You can also click Load Example to load sample data.
2. Choose settings — Select the delimiter (comma, semicolon, tab, or pipe), conversion mode (Standard, Flatten, or Simple), and whether to quote all fields.
3. Convert — Click Convert to CSV to generate the CSV output. The tool handles proper escaping of commas, quotes, and newlines within values.
4. Copy or download — Use the copy button on the output area or click Download .csv to save the result as a file.
