JSON Formatting Guidelines for CSV Conversion

Convert your JSON data to CSV effortlessly by following these supported formats:

  1. Array of Objects: The JSON should contain an array of key-value pairs, making it ideal for structured JSON to CSV conversion.
  2. Single Object: If the JSON consists of a single object with name/value pairs, it will be converted into a single-row CSV file.
  3. Nested JSON with Arrays: When a JSON file contains an object with an embedded array, our converter will extract and flatten the array into structured CSV format.
  4. JSONLines Format (MongoDB-style): Our JSON to CSV converter online also supports JSONLines, where each line contains a separate JSON object.
  5. Custom Array Selection: Easily extract arrays from JSON using JavaScript-style notation, allowing flexible JSON to Excel or CSV exports.
