JSON to CSV Converter

Convert JSON arrays to CSV format with customizable delimiters and options.

About JSON (JavaScript Object Notation)

JSON is a lightweight data-interchange format. It is easy for humans to read and write, and easy for machines to parse and generate. For representing data in tabular format, JSON is typically structured as an array of objects, where each object represents a row and its properties represent the columns.

JSON is widely used in APIs, web applications, and data processing tasks due to its simplicity and compatibility with programming languages.

Example:
[
  {
    "name": "Alice",
    "age": 30,
    "city": "New York"
  },
  {
    "name": "Bob",
    "age": 24,
    "city": "Paris"
  }
]

About CSV (Comma-Separated Values)

CSV is a plain text format that stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas, semicolons, or tabs. The use of delimiters as field separators is the basis for CSV files.

CSV files are widely compatible with spreadsheet applications like Excel, Google Sheets, and many data analysis tools. They are simple, universal, and efficient for data exchange.

Example (from above JSON):
name,age,city
Alice,30,New York
Bob,24,Paris

How to Use This Converter

  1. Prepare your JSON: Ensure your input is a valid JSON array of objects. Each object will become a row in the CSV, and the object keys will become column headers.
  2. Select Delimiter: Choose your preferred delimiter (comma, semicolon, or tab). This depends on your regional settings and the application you'll be using.
  3. Configure Headers: Check the "Include Headers" option to add column names as the first row. Uncheck to skip headers.
  4. Paste JSON: Copy and paste your JSON array into the input text area on the left.
  5. Convert: Click the "Convert to CSV" button to transform your JSON data.
  6. Copy or Download: Use the "Copy" button to copy the result to your clipboard, or click "Download" to save as a CSV file.
  7. Use the CSV: Open the CSV file in your preferred spreadsheet application or data analysis tool.

Delimiter Options

Comma (,)

Most common format, universally supported. Use this for general-purpose CSV files that work with Excel and Google Sheets.

Semicolon (;)

Common in European locales where comma is used as decimal separator. Required for compatibility with some regional Excel settings.

Tab

Tab-separated values (TSV). Useful for data that may contain commas or semicolons, and compatible with many data analysis tools.
