JSON to CSV
Convert JSON objects and arrays into clean, spreadsheet-ready CSV tables. Supports custom delimiters, automatic key extraction, and nested object flattening.
Effortless JSON flattening & key normalization
Real-world API data frequently contains deeply nested structures and sparse fields. FileKinetix automatically unrolls nested JSON objects into clean dot-notation column headers (such as user.address.city) and scans all rows to guarantee that every column aligns accurately across the entire CSV table.
RFC 4180 standard compliance
Values containing commas, line breaks, or double quotes are automatically quoted and escaped according to RFC 4180 standards, ensuring seamless import into Microsoft Excel, Google Sheets, Pandas, and database import utilities.

- Choose your preferred delimiter (Comma, Semicolon, Tab, or Pipe).
- Enable or disable nested object flattening.
- Click 'Convert to CSV' to generate your table.
- Copy the CSV text or click 'Download .csv' to save the file.
