What is a JSON to CSV Converter?

A JSON to CSV converter is a tool that transforms a JSON array of objects into comma-separated values (CSV) format: the universal tabular data format supported by Excel, Google Sheets, databases, and data analysis tools. JSON is great for APIs and web apps, but when you need to analyze data in a spreadsheet or import it into a database, CSV is the standard format.

CodeHelper's JSON to CSV Converter handles nested objects (flattening them with dot notation), custom delimiters, proper CSV escaping for values containing commas or quotes, and generates a downloadable .csv file.

Key Features

  • Auto Column Detection: Extracts all unique keys from the JSON array as CSV columns.
  • Flatten Nested Objects: Converts nested objects into flat columns using dot notation (e.g., address.city).
  • Custom Delimiters: Choose comma, semicolon, or tab as the field separator.
  • Proper Escaping: Values containing delimiters, quotes, or newlines are properly escaped.
  • Download CSV: Export the converted data as a .csv file.

How to use the JSON to CSV Converter

  1. Paste your JSON array of objects into the input.
  2. Configure delimiter and flattening options.
  3. Click Convert to generate the CSV output.
  4. Copy or download the result.

Whether you are exporting API data for analysis, preparing database imports, or converting logs to spreadsheet format, this free tool converts JSON to CSV in seconds.
